 2021 December 26 ILAS-NET Message No. 2378 CONTRIBUTED ANNOUNCEMENT FROM: Tin-Yau Tam SUBJECT: Thomas "Tom" L. Markham (January 2, 1939 - December 20, 2021) With sadness I write to share with you that Professor Thomas “Tom” L. Markham passed away on Monday, December 20, 2021 at the age of 82. Tom received his doctorate degree from Auburn University in 1967 under the supervision of the late Professor Emilie V. Haynsworth (1916-1985). Tom was a professor of Mathematics at the University of South Carolina (USC) from 1968 to 1999 and he was the undergraduate director of Mathematics at USC from 1996 to 1999. He retired as Distinguished Emeritus Professor in 1999. Tom was an active member of the community. He continued to publish a good number of papers in Linear Algebra after his retirement. Below is his obituary: https://www.legacy.com/us/obituaries/newsobserver/name/thomas-markham-obituary?id=31962370 He will be greatly missed by his family, students, friends, and colleagues. 2021 December 18 ILAS-NET Message No. 2377 CONTRIBUTED ANNOUNCEMENT FROM: Naomi Shaked-Monderer SUBJECT: New Book: Copositive and Completely Positive Matrices New book information: Copositive and Completely Positive Matrices by Naomi Shaked-Monderer and Abraham Berman World Scientific Publishing Company, Singapore, 2021, Pages: 564.

If your name is on the list, then you are a member and will be sent the voting instructions by email. 2) If you are not listed on the current online list of members at https://ilasic.org/current-members/, and you believe you are a member because you filled in an online form to join (and made any payment that was due), please email the Secretary/Treasurer Minerva Catral (ILASsecretarytreasurer@gmail.com). Please state when you joined or last renewed and your type of membership (regular = $40/year, life, or fee waiver). If you have an e-mail confirmation of payment it would help to forward that, but it is not necessary. 3) Receiving ILAS-net messages, including this one, does not imply you are an ILAS member. 2021 December 01 ILAS-NET Message No. 2370 CONTRIBUTED ANNOUNCEMENT FROM: Judi McDonald SUBJECT: Linear Algebra Education Seminar - Dec. 7, 2021 The ILAS Education Committee (ILAS‑ED) is hosting a Linear Algebra Education Seminar. We meet virtually on the first Tuesday of every month at 8am Pacific Time. Note that Pacific Time fell back by one hour in November, so the relative time of the seminar mayhave changed in your time zone. Normally, each event will feature a 45‑minute presentation followed by a social half‑hour where participants can ask the speaker(s) questions and visit with other participants. Join us for the opportunity to network and discussbest practices for teaching linear algebra. To suggest a speaker or request a topic, or for more information, please email Judi McDonald at JudiJMcDonald@gmail.com. Our inaugural speaker was Guershon Harel, who spoke On the Complexity of "Simple" Linear‑Algebraic Concepts. Our second talk was given by David Plaxco, who discussed joint work with Christine Andrews-Larson, Megan Wawro, and Michelle Zandieh on Current Workin the Inquiry-Oriented Linear Algebra (IOLA) Project. Our third seminar featured Leslie Hogben and Maria Trigueros discussing mentoring graduate students. You can view the recordings or download the slides at the ILAS-ED seminar page: https://la-education.oucreate.com/monthly-seminar/ Our next seminar will be given by Helena Smigoc: Nonnegative Factorization of a Data Matrix as a Motivational Example for Basic Linear Algebra Linear algebra is a classical subject routinely taught to students not majoring in mathematics. As lecturers we are tasked to motivate our subject by producing convincing and interesting examples that are still within the understanding and knowledge of ourstudents. In this talk we will present a motivating example in which matrix multiplication is explicated by examination of a nonnegative decomposition of a term-by-document matrix. We will explore the meaning of the entries in the decomposition, find naturalinterpretations of intermediate quantities that arise in several different ways of writing the matrix product, and show the utility of various matrix operations. This example gives the students a glimpse of the power of an advanced linear algebraic techniqueused in modern data science. Please join us at 8am PST, December 7, 2021 through the zoom link provided at https://la-education.oucreate.com/monthly-seminar/ There is a waiting room set up to enter the seminar.

Our inaugural speaker is Guershon Harel, who will be speaking on On the Complexity of “Simple” Linear-Algebraic Concepts Why do students encounter major difficulties grasping seemingly simple concepts, such as “span”, “linear independence”, “basis”, “matrix representation of a linear transformation”, etc.? and what instructional approaches found to be effective in helping students reason linear algebraically? The talk will be organized around two themes: (1) Sources of students’ difficulties, such as inadequate attention to conceptual understanding; hodgepodge of concepts, ideas, and symbolism disconnected from students’ prior knowledge; and lack of concrete algebraic models from which students can abstract concepts and ideas. (2) An instructional approach that puts the students’ intellectual need at the center of the instructional effort.

It is expected that ILAS lecturers will be of the stature of plenary speakers at ILAS conferences and may be supported by up to US1500. Reimbursement guidelines may be obtained from the Secretary/Treasurer. • General support of conferences of up to$750. Such support could be used for support of student expenses, expenses for participants from developing countries, or plenary speakers. Refreshment costs are not eligible. You are welcome to consult the President of ILAS about what you may propose. This is a reminder that there is a deadline of 30 September 2021 for receipt of proposals for sponsorship of ILAS Lectures at non-ILAS meetings and for general support of conferences taking place in 2022. Please note that we will not be able to consider applications submitted after the deadline as it is important to rank all applications in one go. Each proposal is automatically assumed to be also a request for the ILAS endorsement of the conference. Further details on the guidelines for proposals can be found at the following link: https://ilasic.org/non-ilas-guidelines/. In addition, ILAS may endorse a Non-ILAS conference, without financial support. Such endorsed meetings can list ILAS' endorsement on their website, and in turn, the conferences are listed on the website of ILAS-Endorsed Meetings: https://ilasic.org/misc/meetings.html 2021 July 27 ILAS-NET Message No. 2350 CONTRIBUTED ANNOUNCEMENT FROM: Thomas Mach SUBJECT: GAMM/ANLA Workshop, Potsdam September 2021 GAMM Workshop on Applied and Numerical Linear Algebra September 16th—17th September 2021 We intend to hold the GAMM ANLA 2021 workshop at the University of Potsdam in September in person. We are aware that the pandemic situation is still ongoing but the situation has substantially improved, and we are hoping for an even better situation in (and lots of vaccinations by) September, and a lot of keen researchers who are eager to finally present their work in person again. The workshop is devoted to all aspects of applied and numerical linear algebra. The topics include but are not limited to: eigenvalue problems, matrix functions, linear systems, least squares problems, tensor methods, matrix equations, high performance computing, inverse problems, and applications. We will take extra precautions to ensure a safe workshop. We expect all participants to be fully vaccinated. Participants will have to physically distance themselves at all times. Since the workshop is usually small, the participants will be seated in the lecture hall 3 or 4 seats apart. Due to new or ongoing restrictions regarding events or travel, we may have to cancel the workshop possibly on short notice. Thus, we will not have invited speakers this year. However, we strongly encourage contributed submissions, in particular by young researchers. We do not assume any liability for costs incurred due to cancellation. We strongly encourage you to book only refundable tickets and accommodation. Contributed talks are welcome, deadline: August 31st, 2021 Deadline for registration: August 31st, 2021 Further details are available at https://sites.google.com/view/gammanla2021/ We look forward to welcoming you to Potsdam, Germany, in September! Melina Freitag and Thomas Mach 2021 July 07 ILAS-NET Message No. 2349 CONTRIBUTED ANNOUNCEMENT FROM: Daniel Szyld SUBJECT: Call for nominations, ICIAM Olga Taussky-Todd Lecture 2023 Dear ILAS members and friends: The nomination for the ICIAM Olga Taussky-Todd Lecture 2023 is now open. https://iciam.org/iciam-olga-taussky-todd-lectures I encourage you to nominate your favorite woman researcher. See the above link for more information. Deadline for nominations is 31 December 2021. The lecture will take place at the next ICIAM in Tokyo in August 2023. 2021 June 15 ILAS-NET Message No. 2348 CONTRIBUTED ANNOUNCEMENT FROM: Wim Michiels SUBJECT: Faculty position, KU Leuven, Belgium Faculty Position, Numerical Methods for Large-Scale Inverse Problems and Data Assimilation, KU Leuven, Belgium The research unit NUMA, Department of Computer Science, KU Leuven, invites applications for a full-time faculty position. The research unit covers many aspects of numerics, including approximation theory, numerical integration, numerical (multi)linear algebra, numerical PDEs, uncertainty quantification, optimization and control, discrete optimization and scheduling, network problems, data science, HPC and applied numerical mathematics. The recent surge in advanced techniques for data acquisition gives rise to computational tasks of a complexity far beyond numerical simulation as integrating measurement data in complex models requires specific numerical algorithms. In the simplest setting, finding the “best” model parameters given some measurement data is an optimization problem. However, demands of practical applications often go far beyond this optimization: one can, for instance, also be interested in quantifying the uncertainty on the resulting optimum, the remaining modeling error with respect to the physical system, or the evolution of the model as a function of time (if data is continuously gathered). The new faculty position aims to strengthen NUMA's position in scientific computing towards a data rich environment. The successful candidate is expected to develop a research program in inverse problems and data assimilation, ensure high-quality education within the area of mathematical engineering, and be prepared to provide scientific, social and administrative services. For further details, contact information and the application procedure follow the link: https://www.kuleuven.be/personeel/jobsite/jobs/60021670?hl=en&lang=en Deadline for applications: October 11, 2021 2021 June 01 ILAS-NET Message No. 2347 CONTRIBUTED ANNOUNCEMENT FROM: Louis Deaett SUBJECT: IMAGE 66 - the Spring 2021 bulletin of ILAS is online now! Inside the new issue of IMAGE, you can read a wide-ranging interview with Richard Brualdi. You can also hear from Sepideh Stewart, the new chair of the ILAS Education Committee, about where research in linear algebra education has been and where it may be going. See if you can help solve a 60-year-old open problem by finding a commuting triple of n-by-n matrices generating an algebra of dimension greater than n.

In particular kudos to Federico Poloni who did a lot of the hard work. 2021 May 26 ILAS-NET Message No. 2345 CONTRIBUTED ANNOUNCEMENT FROM: Hugo Woerdeman SUBJECT: Minutes of the 2021 ILAS Business Meeting 2021 ILAS BUSINESS MEETING Friday May 14, 2021 Virtual via Zoom Agenda: A. Reading of Notice of Meeting. B. Review of the Minutes of Previous Meeting. C. Report of President and Vice President. D. Report of Secretary/Treasurer. E. Reports of Committees. i) Education Committee (chair: Sepideh Stewart) ii) Outreach and Membership Committee (chair: David Watkins) iii) Journal Committee (chair: Beatrice Meini) iv) Electronic Journal of Linear Algebra (Editors: Froilán Dopico & Michael Tsatsomeros) v) IMAGE (Editor: Louis Deaett) F. Transaction of Other Business. i) Future ILAS meetings ii) Any other business G. Adjournment. Minutes of the ILAS Business meeting held on Friday May 14, 2021, virtual via zoom. President Szyld called the meeting to order at 11:01 am EDT. President Szyld observed that we met the quorum, as stated in the revised bylaws. These revisions were prepared by a committee with members Leslie Hogben, Peter Šemrl, and Hugo Woerdeman. The attendance during the meeting ranged between 51 to 56 ILAS members. A. Reading of notice of meeting. B. Review of the minutes from the previous meeting. Minutes of the 2019 Business Meeting held in Rio de Janeiro, Brazil, were approved. C. Report of President and Vice-President President Szyld started by thanking (i) Former President Peter Šemrl for leaving ILAS in wonderful shape and keeping him on track; (ii) Vice President Hugo Woerdeman for being a fantastic partner; and (iii) Former Secretary/Treasurer Leslie Hogben for providing a steady hand, a well of knowledge, and a source of sage advice. Next, President Szyld highlighted the Wikipedia page and the newly designed webpages. He pointed out that the new webpages were the results of a big effort with Dominique Guillot providing instrumental help with the overall design and implementation, with Vice-President Hugo Woerdeman masterminding the effort, and with continued strong support by ILAS-NET and ILAS Website Manager Sarah Carnochan Naqvi. Dominique Guillot and Pietro Paparella joined the ILAS-NET/Website team as Assistant Managers. President Szyld also highlighted the newly introduced Facebook and Twitter pages, which Outreach and Membership Director David Watkins would discuss later on. President Szyld announced that the board approved a new prize, the ILAS Richard A. Brualdi Early Career Prize, which will be awarded to someone within 7 years of their PhD. For the first installment it will be someone who received their PhD between 2015 and 2022, and he encouraged members to start thinking about possible nominations. In addition, the Board approved the proposal to change the Taussky-Todd Lecture to the ILAS Taussky-Todd Prize. Together with the ILAS Richard A. Brualdi Early Career Prize and the Hans Schneider Prize, ILAS now has a triplet of prizes President Szyld continued to discuss the upcoming conferences, with the ILAS 23/SIAM-LA21 meeting next week, the ILAS 24 Galway meeting in June 2022, and the ILAS 25 Madrid meeting in June 2023. For 2025 Szyld and Vice-President for Conferences Raf Vandebril are starting to consider options, and the membership is welcome to put forward ideas and proposals. Next, President Szyld mentioned that ILAS is now a partner at the Joint Mathematics Meetings (JMM). For JMM 2022 the board chose Pauline van den Driessche as the first ILAS Lecturer at the JMM, and in addition there will be ILAS Special Sessions. In response To Kevin vander Meulen’s question what the financial commitment is, President Szyld answered that ILAS will contribute \$1000 to the meeting as well as cover the expenses of the ILAS Lecturer. D. Report of Secretary/Treasurer. Former Secretary/Treasurer Hogben mentioned that this will be a shared presentation with Secretary/Treasurer Catral as the transition to the new Secretary/Treasurer was very recent. Hogben continued to present the Treasurer’s Report, which will be published in IMAGE 66, and indicated that ILAS is in good financial state that grew in the last year from about \$200K to the current balance of about \$210K. It was reiterated that as a general rule ILAS is aiming to spend what comes in, as a non-profit organization should. This past year, however, the expenses were close to zero as conferences were cancelled or went virtual. A new expense is the copy-editing of ELA. Secretary/Treasurer Catral continued and mentioned that: • ELA started to use a private company Lumina to do the copy-editing. • The payment options for members now include PayPal and credit card payments via PayPal. • Processing new members takes time and is typically done once a month. Thus it takes some time before new members show up on the webpages. Secretary/Treasurer Catral asks the membership to keep this in mind, and to please be patient. Secretary/Treasurer Catral expressed appreciation for donations that were received, and mentioned that the ILAS Richard A. Brualdi Early Career Prize Fund is a new addition to the list of funds. E. Reports of Committees. i. Education Committee The Education Committee is composed of Anthony Cronin, Judith McDonald, Rachel Quinlan, Sepideh Stewart (chair), and David Strong. Chair Stewart reported for the committee mentioning that (i) The new Education Committee was appointed in February 2021 and that they had monthly committee meetings since as well as other discussions. (ii) Anthony Cronin is now the editor in charge of the education portion of the IMAGE bulletin. (iii) They are in the process of designing education pages for ILAS website, which will be forwarded to the Board. (iv) Weekly seminars are being planned starting Fall 2021. (v) The committee is involved in organizing workshops, including a Mini-Symposium at ILAS 23/SIAM-LA21 (“Linear Algebra Education for the Modern World”) and a Mini-Symposium at ILAS 2022 (Anthony Cronin and Sepideh Stewart are co-organizers of this session, and currently, 12 speakers are invited to present at the conference). The committee is excited and dedicated to focus on ILAS and its goals and find ways of serving the ILAS community. The committee encourages comments and suggestions from ILAS. ii. Outreach and Membership Committee The committee is composed of Minerva Catral, Andrii Dmytryshyn, Federico Poloni, and David Watkins (chair). Outreach Director Watkins reported for the committee, and mentioned that (i) in Summer 2020 the committee started a membership drive, sending out nearly 1000 letters to Linear Algebraists who are not current members of ILAS, inviting them to join. The ILAS-Net mailing list was a good resource for identifying potential members. Former Secretary/Treasurer Hogben observed that the membership drive led to several new members. The committee is currently collecting names of potential new members by, for instance, going through Linear Algebra journals. Outreach Director Watkins encouraged ILAS members to inform the committee of potential new members the committee could contact. Watkins continued reporting that the committee started a Facebook page and a Twitter account, and he encourages ILAS members to be a follower via Facebook and Twitter, and contribute posts and send retweets with comments. In addition, he hopes that after Galway there will be new pictures to post. The committee is also in the process of extending our presence on Wikipedia, and collaborate with Beatrice Meini, chair of the Journals Committee, to make an ELA page on Wikipedia. It was mentioned that Linear Algebra and its Applications has a Wikipedia page. Finally, the committee is always looking for new corporate sponsors, and hopes to score the MathWorks as a new sponsor. The ILAS members are encouraged to let the committee know of potential sponsors. Vice-President Woerdeman mentioned that he noticed that a Wikipedia page on the Hans Schneider Prize predated the ILAS Wikipedia page, and wondered if anyone knew who initiated this. Federico Poloni noticed that the initiator wrote several other Wikipedia pages on prizes in Mathematics. iii. Journals Committee The Journals Committee is composed of Louis Deaett (for IMAGE), Froilán Dopico (for ELA), Chi-Kwong Li, Beatrice Meini (chair), and Peter Šemrl. Chair Meini reported for the committee, starting off with mentioning that the ILAS bulletin IMAGE has interesting articles on activities, interviews, reports, and other items, and that it is doing well. At the moment no new actions are planned regarding IMAGE. Chair Meini continued, discussing the Electronic Journal of Linear Algebra (ELA) - the ILAS research journal, and our flagship publication. It is fully open access (no charges for authors/readers). The goal is to make the journal more attractive for authors and to continue to raise the quality of the journal. The actions that are planned are: (i) advertise the journal, for instance, by creating a Wikipedia page for the journal. (ii) to improve the editorial process (e.g., faster publication times – professional copy-editing supported by ILAS and voluntary donations). In addition, the following actions were taken regarding the editorial board, allowing for a continuous change in editors as well as bringing in younger researchers to the editorial process: • The President shall appoint at the direction of the Board of Directors and after consultation with the Journal Committee not more than 2 Editors-in-Chiefs (EiCs) for 3-year terms. The EiCs may not serve more than 2 consecutive terms. • The EiCs shall appoint Advisory Editors for 3-year terms after consultation with the Journal Committee. The Advisory Editors should normally not serve for more than 3 terms. Appointments, renewals, as well as exceptions to the term limit rule, must be approved by the Journal Committee. • The EiCs shall appoint Associate Editors for 3-year terms after consultation with the Journal Committee. The Associate Editors should normally not serve for more than 2 terms. Appointments, renewals, as well as exceptions to the term limit rule, must be approved by the Journal Committee. • Once a year, the EiCs shall present a report to the Board of Directors (to be discussed with the Journal Committee) on the operation of the journal since the last such report. Chair Meini encouraged all ILAS members to submit their papers to ELA, and added that the journal has great editors. ILAS member Nair Abreu noted that in Brazil open access journals are perceived as having low quality. President Szyld responded that those journals that have page charges are perceived in that way, but that ELA does not have page charges. iv. ELA Editor-in-Chief Michael Tsatsomeros reported for ELA. He started out by saying that since the beginning of 2020 ELA has moved online editorial platforms from BePress to Open Journal Systems (OJS). It required a significant effort from all members of the Editorial Board in order to transfer records and adapt to the new environment. Tsatsomeros thanks everyone for their efforts. Next, he wants to express that ELA must prioritize and strive toward the following goals: • Seek greater quality of papers and journal reputation as measured by citations, journal metrics and ranking. Currently, the manuscripts received vary widely in quality as well as in classification. Increasingly, received manuscripts do not fit well in the journal. • Steer ELA to better reflect and influence the research trends in linear algebra and its applications. • Attract greater participation in the content of ELA by ILAS members. Tsatsomeros expressed that the Editors-in-Chief along with the editors aim to be more selective, focusing on modern research and try to improve citations. It continues to be important to receive good papers, which will increase the quality, resulting in more good papers, etc. Tsatsomeros appealed to the membership to trust the direction of ELA and to submit strong papers. He acknowledged that compared to LAA, LAMA and SIMAX, the Electronic Journal of Linear Algebra does have some disadvantage as it does not have the recognition of a well-known publisher behind it. In addition, Tsatsomeros mentioned the pursuit of the CNKI (Chinese scholar indexing), which may help to increase ELA’s exposure in the Chinese research community. Tsatsomeros’s term limit as EIC will end in February 2022, but he will stay available to continue to help with ELA’s development, and asks the ILAS membership for help in supporting ELA. President Szyld asked what the percentage of papers is that is rejected outright. In 2020 there were 138 out of 219 papers that were rejected outright, which represents a percentage of 63%. The overall rejection rate is about 70%. Vice-President Woerdeman offered that having made ELA more prominent on the new webpages will hopefully also help ELA. Tsatsomeros finished by thanking all the editors for their service. President Szyld reiterated this sentiment and also thanked Editors-in-Chief Froilán Dopico and Michael Tsatsomeros for all their hard work. v. There was no separate report on IMAGE. F. Transaction of other business i) Future ILAS meetings Vice-President for Conferences Vandebril started out by mentioning that the Galway meeting was postponed from 2020 to 2022, and that the Madrid meeting was moved from 2022 to 2023. He thanked the organizers for handling these changes. He continued, mentioning that next week the combined ILAS 23/SIAM-LA21 will take place, and that (i) out of the 88 minisymposia, 11 are designated as ILAS ones; (ii) out of the 72 contributed talks, 8 are designated as ILAS ones; (iii) out of the 14 plenary talks, 4 are designated as ILAS ones. In addition, many participants are identified as ILAS participants. At the time of this writing, it was additionally reported that out of the 324 minisymposia talks, 47 were designated as ILAS. Next, he introduced Rachel Quinlan, organizer of the 24th ILAS meeting, which will be held at National University of Ireland, Galway, June 20-24, 2022. Quinlan expressed gratitude to many of the main speakers who were flexible in moving their talk to 2022. There will be some changes, though, especially regarding the special lectures as some will happen at ILAS 23/SIAM-LA21. Many minisymposia will also be moved from 2020 to 2022, and there will be a call for contributed minisymposia. She also mentioned some favorable features of the town and the conference site, and encourages ILAS members to check the conference website, ilas2020.ie, where also pandemic related and/or potential virtual component announcements will appear. She expressed the hope to see many in person in Galway. Board member Sebastian Cioabă and ILAS member Nair Abreu subsequently expressed similar sentiments. To discuss the 25th ILAS meeting Organizer Fernando De Terán was given the floor. ILAS 25 will be held at Universidad Nacional de Educación a Distancia (UNED), Madrid, Spain, June 5-9, 2023, a time when the temperatures are typically still pleasant. The location is on the west side of the side of the city, easily accessible from the center of Madrid by public transportation. Support from local government has been promised including a special venue for the banquet and/or the reception: Cecilio Rodríguez Pavillion (Retiro Garden). Next, the local and scientific organizing committees were introduced. They will be working on the webpage, the selection of plenary speakers, and the invited minisymposia. G. Adjournment After wishing everybody a good conference the following week, President Szyld adjourned the meeting at 12:07 pm EDT. Respectfully submitted by Hugo Woerdeman, Vice-President of ILAS. 2021 May 25 ILAS-NET Message No. 2344 CONTRIBUTED ANNOUNCEMENT FROM: Andrii Dmytryshyn SUBJECT: V.V.

The revised By-laws have been approved by the ILAS Board of Directors, and are now posted on the ILAS Website. Please let us know if you have any questions or comments. Daniel B. Szyld ILAS President 2021 April 04 ILAS-NET Message No. 2336 CONTRIBUTED ANNOUNCEMENT FROM: Hugo J. Woerdeman SUBJECT: 2021 ILAS Business Meeting You are hereby invited to attend the 2021 ILAS BUSINESS MEETING Friday May 14, 11am EDT Virtual via zoom (details to be provided) Agenda: A. Reading of Notice of Meeting. B. Review of the Minutes of Previous Meeting. C. Report of President and Vice President. D. Report of Secretary/Treasurer. E. Reports of Committees. i) Education Committee (chair: Sepideh Stewart) ii) Outreach and Membership Committee (chair: David Watkins) iii) Journal Committee (chair: Beatrice Meini) iv) Electronic Journal of Linear Algebra (Editors: Froilan Dopico & Michael Tsatsomeros) v) IMAGE (Editor: Louis Deaett) F. Transaction of Other Business. i) Future ILAS meetings ii) Any other business G. Adjournment. Below are the minutes of the 2019 Business Meeting _______________________________________________________ Minutes of the ILAS Business meeting held on Thursday July 11, 2019, Main Auditorium, Fundação Getúlio Vargas (FGV), Rio de Janeiro, Brazil President Semrl called the meeting to order at 6:00 pm. About 55 ILAS members were in attendance. A. Reading of notice of meeting. B. Reading of the minutes from the previous meeting. Minutes of the 2017 Business Meeting held in Ames, Iowa, were approved. C. Report of President and Vice-President President Semrl reported on items that were new since the last President and Vice-President report that was published in the 2019 Spring issue of IMAGE. The Board approved the proposal to hold the ILAS 2022 conference in Madrid. The organizers will present the proposal later in the meeting. The Board approved a change to the 'Guidelines for the Hans Schneider Prize' allowing for a medal instead of a plaque. The Board approved pursuing a Wikipedia page for ILAS. The page will contain material that does not require updating. Wayne Barrett will lead a team to provide content for the page. A volunteer from the membership will be needed to provide technical support to create and seek publication of the Wikipedia page. Those interested are encouraged to contact President Semrl. More items were discussed at the board meeting, but those issues have not reached a conclusion yet. When they do, the membership will be informed. D. Report of Secretary/Treasurer. Treasurer Hogben presented the Treasurer's Report, which was published in IMAGE 62, and indicated that ILAS is in good financial state with a current balance of ~186K. It was reiterated that as a general rule ILAS is aiming to spend what comes in. In recent years support of conferences has increased. Treasurer Hogben introduced newly appointed Assistant Secretary/Treasurer Minerva Catral. Daniel Szyld initiated a round of applause in recognition of Treasurer Hogben's dedicated service. E. Reports of Committees. i. Education Committee The Education committee is composed of Avi Berman, Steve Leon, Sepideh Stewart, and David Strong (chair). As no committee member could be present at the business meeting, Chair Strong provided slides to be presented at the meeting. The slides showed three notable activities since the 2017 ILAS Business Meeting: Articles on Linear Algebra education in IMAGE Sessions on "Innovative and Effective Ways to Teach Linear Algebra" at 2018 and 2019 Joint Meetings of the AMS and MAA National Pedagogical Initiatives on Linear Algebra The committee encourages comments and suggestions from ILAS members on furthering the teaching, learning and exploration of Linear Algebra. ii. Institutional Membership Committee The committee is composed of Minerva Catral, Heike Faßbender, Yongdo Lim (chair), and Peter Semrl (ex-officio). Heike Faßbender reported for the committee. The current institutional members are: Elsevier; Pearson; World Scientific; SIAM; CRC Press; Taylor and Francis; Maplesoft, and Birkhäuser/Springer. Birkhäuser/Springer is a new addition due to the Israel Gohberg ILAS-IWOTA Lecture series, which was approved by the ILAS board in 2017. Faßbender reported that the committee has tried to attract non-US based sponsors, but while these were happy to provide funds for ILAS conferences they were not inclined to become an Institutional Member of ILAS. While one may stay on the lookout for new Institutional Members, it may be advisable for the committee to focus on keeping the current Institutional Members well engaged. The committee expressed that help from any ILAS member in these efforts is very welcome. iii. Journals Committee The Journals Committee is composed of Rajendra Bhatia (chair), Geir Dahl, Froilán Dopico, Michael Tsatsomeros (ex-officio), and Louis Deaett (ex-officio). Tsatsomeros reported for the committee. Tsatsomeros reported that Bryan Shader has expressed the desire to step down as Editor-In-Chief of ELA at the end of his term in October 2019. ILAS and the Journals Committee are considering a replacement. Tsatsomeros continued, reporting for ELA. iv. ELA Editorial Board: Editors-in-Chief (Bryan Shader and Michael Tsatsomeros), 7 Advisory Editors, 16 Associate Editors, an Associate Managing Editor and an Assistant Managing Editor. The ELA annual budget of $3500 from ILAS can be spent at the discretion of the Editor(s)-in-Chief of ELA for operational expenses related to copy editing, plagiarism checking, and maintenance of the ELA portal, as well as travel for the Editors-in-Chief and Managing Editors to attend ILAS conferences and SIAM ALA conferences. The OverLeaf platform that is currently free, may start charging fees. Milestone ahead: ELA is approaching 1,000 papers published since 1996. Suggestions for a celebration are welcome. Richard Brualdi noted that ELA's 25th anniversary is coming up in 2021, and that one could consider a satellite meeting to SIAM-LA 2021 to celebrate this. Other disciplines have done this. To date over 185,000 papers from over 5,800 institutions and 184 countries have been downloaded from the ELA portal. 48,000 downloads of ELA papers occurred in the last year. ELA receives about 250 submissions per year. Each volume has about 50 papers. Tsatsomeros expresses the desire to receive more submissions from core ILAS members. About 90% of the authors he does not know. Time from submission to publication for a regular volume is about 9-10 months. While not bad considering ELA is run by volunteers, Tsatsomeros hopes to reduce this time in the future. Tsatsomeros discusses some metrics, comparing them to LAA, LAMA, Operators & Matrices, Special Matrices, and SIMAX. For instance, the SNIP (=normalized impact factor) 2017 for ELA is 0.886, while for the others the SNIP is 1.185, 0.951, 0.656, 0.481 and. 1.747, respectively. Other metrics show similar results. While exact interpretation of these numbers is hard, it does seem to indicate that it is fair to say that ELA is at a competitive footing among the leading linear algebra journals. The number of total ELA citations shows an upward trend, with over 500 for 2017. It is expected that two members of the editorial board will step down in the near future. Currently ELA has no policy on education oriented papers. The editorial board will have to discuss this. After it was brought up, Volker Mehrmann confirmed that LAA does not publish educational oriented papers. Daniel Szyld suggested that other journals are focused on educational papers, and that ELA should continue to focus on research papers. Tsatsomeros reiterated that a discussion in the Editorial Board on this topic will be pending, and that one can also consider special issues focused on educational papers. Volker Mehrmann asked whether the current website set-up of ELA is sustainable. Tsatsomeros answered that Shader will continue as Managing Editor, and that he is committed to continue to contribute to ELA, and that the University of Wyoming website will continue to serve as the ELA website. Volker Mehrmann brought up that Plan S, an initiative for open-access science publishing, is emerging, and that ELA should consider collecting open access fees from those authors willing and able to pay such funds. In addition, he made the point that for some, when they pay for services, it makes the service more valuable to them. Tsatsomeros said that the Editorial Board will consider this. Sebastian Cioaba asked about accessibility of papers to readers with disabilities, noting that accessibility of teaching materials is increasingly a concern for universities. Daniel Szyld added that in use of colors, the color blind should be taken into account. Tsatsomeros responded that this is an issue to look into, and that it may require an appropriate version of LaTeX. v. Report on IMAGE Editor-in-Chief, Louis Deaett. Former Editor-in-Chief, Kevin Vander Meulen, reported. Vander Meulen started by expressing his gratitude to the members of the editorial board for their service. Vander Meulen reported that the creation of a book of problems and solutions based on the problem section of IMAGE, is an ongoing project. Rajesh Pereira, who is in charge of the project, has talked to various publishers, and details still need to be worked out. The number of downloads of IMAGE continue to go up, currently about 1500 per year. Mysteriously, issue 45 remains one of the most popular, perennially averaging over 1000 downloads per year. Possible explanations are welcome. Colin Garnett began a term as editor for book reviews with IMAGE 60, replacing Doug Farenick. Naomi Shaked-Monderer ended her tenure as editor of the history section with IMAGE 61. No replacement has currently been found. If anyone is interested, please contact Editor-in-Chief Deaett. Minerva Catral stepped down as editor for conferences after IMAGE 59. For issues 60 and 61, Jillian McLeod served as conferences editor. She has been unable to continue serving in this capacity, and IMAGE 62 went without a dedicated member of the staff responsible for this section. Again, if anyone is interested to serve in this role, please contact Editor-in-Chief Deaett. IMAGE is also looking to diversify geographically, and especially encourages potential contributors from a continent other than North America. Sebastian Cioaba, who handles feature articles, asked for suggestions for future feature articles. President Semrl suggested to put out a call via ILAS-Net. President Semrl noted that all those involved in ELA and IMAGE do hard work. F. Transaction of other business i) Future ILAS meetings The 23st ILAS meeting will be held at National University of Ireland, Galway, June 22-26, 2020. Organizers Rachel Quinlan and Helena Smigoc advertised the conference website, ilas2020.ie. They encouraged suggestions that will be helpful to make the conference a success, and they announced that a call for minisymposia will go out soon. They encouraged all ILAS members to come to ILAS 2020. The 24th ILAS meeting will be held at Universidad Nacional de Educación a Distancia (UNED), Madrid, Spain, June 6-10, 2022. Organizers Fernando De Terán and Roberto Canogar presented impressions of the city of Madrid, which were welcomed by the membership. Vilmar Trevisan asked about the envisioned registration fee, to which De Terán answered that they hope to be in the same ballpark as ILAS 2019. Sebastian Cioaba expressed the concern that the ratio of female vs male plenary speakers at ILAS conferences was perhaps somewhat at the low end. President Semrl noted that in the 'Guidelines for the Organization of ILAS Meetings' diversity in various ways is a requirement for a successful conference proposal. Aside from diversity in gender, it also addresses diversity in topics, diversity of career stage, and geographical diversity. In addition, organizing committees are required to show diversity. Having said that, President Semrl continued, the ILAS Executive Board is always interested in feedback from the membership when specific concerns arise. ii) Other business Vice President Woerdeman, noting that this is Semrl's last ILAS business meeting as President, initiated a round of applause showing appreciation of President Semrl for his dedicated service. G. Adjournment President Semrl adjourned the meeting at 7:21 pm. Respectfully submitted by Hugo Woerdeman, Vice-President of ILAS. 2021 April 03 ILAS-NET Message No. 2335 CONTRIBUTED ANNOUNCEMENT FROM: Bruno Iannazzo SUBJECT: Matrix Equations and Tensor Techniques Workshop, Perugia, Italy, September 9-10, 2021 The next Matrix Equations and Tensor Techniques Workshop will be hosted on Thursday and Friday 09-10 September 2021 in Umbria, Italy, at the Department of Mathematics and Computer Science of the University of Perugia.

Daniel Szyld ILAS President 2021 March 14 ILAS-NET Message No. 2330 CONTRIBUTED ANNOUNCEMENT FROM: Daniel Szyld SUBJECT: ILAS Lectures at Non-ILAS Conferences and a General Support of Non-ILAS Conferences As part of ILAS's commitment to supporting activities in Linear Algebra, the Society maintains a program of providing some support to non-ILAS conferences. This support may take one of two forms (a conference may apply for only one of these two forms). ILAS Lectureships at non-ILAS conferences. It is expected that ILAS lecturers will be of the stature of plenary speakers at ILAS conferences, and may be supported by up to US$1000 for expenses, or in the case of a Hans Schneider Lecturer, US$1500. Reimbursement guidelines may be obtained from the Secretary/Treasurer Minnie Catral. General support of conferences of up to$750. Such support could be used for support of student expenses, expenses for participants from developing countries, or plenary speakers. Refreshment costs are not eligible. You are welcome to consult the President Daniel B. Szyld about what you may propose. This is a reminder that there is a deadline of 30 September 2021 for receipt of proposals for sponsorship of ILAS Lectures at non-ILAS meetings and for general support of conferences taking place in 2022. Please note that we will not be able to consider applications submitted after the deadline as it is important to rank all applications at once. Each proposal is automatically assumed to be also a request for the ILAS endorsement of the conference. Further details on the guidelines for proposals can be found at the following link: https://ilasic.org/misc/non_ilas_guidelines.html 2021 March 14 ILAS-NET Message No. 2329 CONTRIBUTED ANNOUNCEMENT FROM: Daniel Szyld SUBJECT: Panel on Transforming Learning and Teaching Linear Algebra On May 6, 3:30-5pm ET there will be a panel discussion on the topic Transforming Learning and Teaching Linear Algebra hosted by the MAA. Panelists are: Sheldon Axler, Eugene (Bud) Boman, Minerva Catral, Guershon Harel, Judi McDonald, Sepideh Stewart, Gilbert Strang, David Strong, Megan Wawro For details, see https://www.maa.org/node/2551705/ 2021 March 04 ILAS-NET Message No. 2328 CONTRIBUTED ANNOUNCEMENT FROM: Fernando De Terán Vergara SUBJECT: Reminder Special Issue of Computational and Mathematical Methods (CMM) This is a reminder on the call for papers for the special issue of the journal Computational and Mathematical Methods (CMM) on Linear Algebra, Matrix Analysis, and Applications https://onlinelibrary.wiley.com/journal/25777408 CMM is an interdisciplinary journal dedicated to publishing the world's top research in the expanding area of computational mathematics, science and engineering. The journal connects methods in business, economics, engineering, mathematics and computer science in both academia and industry. Mathematical modelling of problems arising in engineering, physics, mechanics, etc. leads in many cases, directly or after a discretization process, to solving systems of linear equations of finite dimension. Besides, other problems of Numerical Analysis, such as approximation, interpolation, nonlinear systems, computation of eigenvalues, etc., lead to the resolution of large systems. Thus, it is essential to develop efficient numerical Linear Algebra methods, in both sequential and parallel environments, to solve them. The main purpose of this Special Issue is to collect original contributions about the solution of such problems as well as other applications of Linear Algebra from a multidisciplinary approach. The guest editors of this special issue are Luca Bergamaschi (luca.bergamaschi@unipd.it), Fernando De Terán (fteran@math.uc3m.es), and Pedro Alonso (palonso@uniovi.es). Submission Details: Authors should follow the author guidelines. All papers must be submitted via the online system https://mc.manuscriptcentral.com/compandmathmethods Authors need to make sure they specify that the paper is a contribution for "Special Issue on Linear Algebra, Matrix Analysis and Applications" and select the article type, when prompted. All papers will be peer reviewed according to the high standards of CMM. Deadline for submissions: *June 30, 2021*. We invite you to participate in the Special Issue with a contribution. Best regards. Luca Bergamaschi, Fernando De Terán, and Pedro Alonso 2021 March 04 ILAS-NET Message No. 2327 CONTRIBUTED ANNOUNCEMENT FROM: Ning Zheng SUBJECT: Workshop in honor of Ken Hayami's retirement, March 2021 We are very pleased to announce The 2nd Workshop on Numerical Algebra, Algorithms and Analysis March 16–17, 2021 in honor of Professor Ken Hayami on the occasion of his retirement from the National Institute of Informatics and The Graduate University for Advanced Studies (SOKENDAI), Japan.

Raf Vandebril Vice-president, ILAS 2021 January 26 ILAS-NET Message No. 2322 CONTRIBUTED ANNOUNCEMENT FROM: Daniel Szyld SUBJECT: ILAS Richard A. Brualdi Early Career Prize It is very exciting to announce that ILAS is initiating the ILAS Richard A. Brualdi Early Career Prize. The Board approved this new prize which will be awarded every three years at an ILAS Conference to an outstanding early career researcher in linear algebra, for distinguished contributions to the field within seven years of receiving the PhD or equivalent degree. For complete guidelines, see https://ilasic.org/misc/lecturers.html The prize is named for Richard A. Brualdi, who has been active in ILAS since its inception and who has been and continues to be instrumental to its success. Indeed, in 1987 he was a committee member when the International Matrix Group/The International Linear Algebra Community was established, which soon thereafter became ILAS. He has since served in ILAS in several capacities including as Vice-President (1992-1995) and President (1996-2002). The first ILAS Richard A. Brualdi Early Career Prize will be awarded at the ILAS Conference in Madrid in 2023, where the awardee will also present a plenary lecture. Calls for nomination will go out in 2022. Nominees would have received a doctoral degree no earlier than 1st October 2015. To make a contribution towards the ILAS Richard A.
