Vice-President Dopico observed that about 38 ILAS members were in attendance and that the quorum was met, as stated by ILAS Bylaws. A. Reading of Notice of Meeting President Szyld read the notice of the meeting. B. Review of the minutes of previous meeting Minutes of the 2021 Business Meeting held virtually on Friday May 14, 2021, were approved. C. Report of President and Vice President President Szyld started by reporting that the state of ILAS is strong and that this statement would be supported by the reports of the different committees that will be presented during the meeting. President Szyld reminded that the detailed annual report prepared by Vice-President Dopico and President Szyld was published in the last issue of IMAGE, the biannual bulletin of ILAS, with Louis Deaett as Editor-in-Chief. President Szyld emphasized that 2022 is the third year of his presidency of ILAS, but that the 24th ILAS Conference in Galway is the first in-person conference since he is serving as president. Therefore, President Szyld reported on the following few highlights from the last three years, all of which came, according to President Szyld, from the excellent work made by the Board of Directors and other members of the society. 1- An agreement with the American Mathematical Society was established so that ILAS is a partner with full participation at the Joint Mathematics Meetings (JMM) held every January. In each JMM, ILAS has a plenary speaker and several minisymposia identified with the acronym ILAS. At the next JMM, which will take place in Boston in January 4-7, 2023, the ILAS member Apoorva Khare (Indian Institute of Science, Bangalore) will deliver the ILAS plenary lecture and several minisymposia organized by ILAS members have been approved by the ILAS Vice-President for Conferences Raf Vandebril. President Szyld encouraged the ILAS members to start thinking on proposing minisymposia for the 2024 JMM. 2- The Board of Directors approved the “ILAS Welcoming and Inclusiveness Statement”, which can be found at ILAS Web-site, and could be read in the back of the conference schedule. 3- The Board approved the new “ILAS Grant Program in support of Mathematicians working in Linear Algebra affected by conflicts”, a program of small grants for mathematicians working in linear algebra who are refugees or are fleeing situations of conflict. 4- The society established the ILAS Richard A. Brualdi Early Career Prize, which completes and complements the ILAS set of research prizes. The first ILAS Richard A. Brualdi Prize will be awarded in June 2023 at the 25th ILAS Conference to be held in Madrid. President Szyld reported that the committee for the first prize has been appointed and that the members are Shmuel Friedland (Chair), Marina Arav, and Volker Mehrmann. President Szyld encouraged to read the guidelines of the prize at ILAS Web-site and to nominate strong candidates. 5- President Szyld reported that like every year there will be elections in 2023 and that the nominating committee has been set up with the following members: Raymond Chan, Steve Kirkland (Chair), Beatrice Meini, Bryan Shader and Helena Smigoc. 6- The Board of Directors has approved at its meeting on Tuesday June 21 the membership fees for the next year: For standard members the fee continues to be \$40; for Early career members (within 5 years after the PhD) it is \$20, which represents a 50% discount. In both cases, the fees can be waived annually for people undergoing financial hardship upon request. Students have free membership. D. Report of Secretary/Treasurer Treasurer Catral briefly presented the Treasurer’s Report, which was published in IMAGE 68. She remarked that ILAS is in good financial state with a balance of ~220K on March 31, 2022. Treasurer Catral highlighted the generous donation of 60K received recently from Taylor & Francis, the publisher of LAMA, and that was negotiated by Steve Kirkland. Michael Tsatsomeros asked for the reasons of the donation from Taylor & Francis. President Szyld explained that Taylor & Francis had funded since 2005 the LAMA Lecture at each ILAS Conference and that to ask Taylor & Francis for the funds every time an ILAS Conference was held was time consuming. Thus, Steve Kirkland had the idea of asking Taylor & Francis for a reasonable amount of money whose interests would allow ILAS to fund the LAMA Lectures for the years to come. E. Reports of Committees. i. Education Committee The Education Committee is composed of Anthony Cronin (Ireland), Judi McDonald (USA), Rachel Quinlan (Ireland), Sepideh Stewart (Chair) (USA), and David Strong (USA). The new ILAS Education Committee was appointed and formed in February 2021 and meets monthly. Sepideh Stewart started by reporting on the ILAS-Education Webpages. A proposal for having ILAS-Education Webpages inside the ILAS Web site was accepted by the Executive Board of ILAS. A new Education page was launched in Fall 2021 on the ILAS website. Currently, the only active tab is for Seminars, Conferences, and Workshops, to hold the Monthly Seminars via Zoom. The talks of these seminars are recorded, and links to the recorded seminars and slides are posted on the site. So far, the Education Committee has organized nine seminars. Although the talks have been highly engaging, the attendance at these seminars is lower than anticipated. Sepideh Stewart encouraged the ILAS community to participate in these seminars and contact the committee if some person would like to give a talk. Sepideh Stewart reported that the next ILAS-Education page under construction is “Teacher’s Resources”. The members of the Education Committee are focusing on creating Lesson Plans for teaching linear algebra concepts (at all levels). The success of this page depends on the ILAS communities’ contributions. Sepideh Stewart encouraged the community to write lesson plans and share their ideas and thoughts about teaching various topics. Creating and preserving a record of teaching ideas and experiences will benefit the entire international community of linear algebra. The Education Committee hopes to make this page available this coming Fall. More information will be available soon. Next, Sepideh Stewart reported on education publications. During the past year, IMAGE published three education articles. Anthony Cronin is the education editor of IMAGE. Sepideh Stewart encouraged the ILAS Community to approach him if some person would like to contribute an article. The Education Commitee submitted a proposal to PRIMUS in early June, and it got accepted on June 24, 2022 (one day after this business meeting was held). Established in 1991, Problems, Resources, and Issues in Mathematics Undergraduate Studies (PRIMUS) is a peer-reviewed academic journal covering the teaching of undergraduate mathematics. The members of the Education Committee will act as the guest editors of a special issue of PRIMUS. The Committee will send a call and invite ILAS members to submit linear algebra education papers soon. Sepideh Stewart reported that after hearing Helena Smigoc’s seminar on Modern Linear Algebra Applications, in Spring 2022, the Education Committee met monthly to plan the writing of a Modern Applied Linear Algebra book. The Committee would like to invite all ILAS members to join in with this initiative and send their ideas to the Committee. Sepideh Stewart informed on Conferences as follows. The Education Committee had three sessions (12 talks) at this year’s ILAS conference. The Education Committee organized two sessions in SIAM/LA21 titled Linear Algebra Education for the Modern World (May 17 &18, 2021). These were well attended, and good discussions took place. Sepideh Stewart, Judi McDonald, and Anthony Cronin organized a Linear Algebra Workshop at the Research in Undergraduate Mathematics Education Conference in Boston, USA (February 2022). Judi McDonald and Anthony Cronin discussed parts of their research in linear algebra. For upcoming Conferences, the Committee plans to organize a JMM 2023 – ILAS Education session, and a possible ILAS Education Workshop at the ILAS conference 2023. Sepideh Stewart finished her report by emphasizing that the Education Committee is dedicated to focusing on ILAS and its goals and finding ways of serving the ILAS community. ii. Outreach and Membership Committee The Outreach and Membership Committee is composed of Minerva Catral, Andrii Dmytryshyn, Federico Poloni, and David Watkins (Chair). Andrii Dmytryshyn reported for the committee. The Committee is actively inviting people to join ILAS. A total of 1140 invitation letters have been sent, some to persons suggested by ILAS Members. The ILAS Corporate sponsors (Silver US \$200/yr; Gold US \$ 300/yr; Diamond more) are 1. Birkhäuser/Springer (Gold) 2. Elsevier Science, Inc. (Diamond) 3. Taylor & Francis Group - Informa UK Ltd. (Diamond) 4. MathWorks is a new corporate sponsor (Gold) 5. World Scientific Publishing Co. (Gold) 6. Maplesoft (Silver) The Committee created, and is maintaining, Wikipedia pages for ILAS and ELA, in a joint effort with other committees and individuals. The Committee handles the social media presence of ILAS in Facebook and Twitter. Andrii Dmytryshyn finished his report by encouraging the audience to contact the Committee with suggestions of people that might want to join ILAS and asking the audience for encouraging their students to join ILAS (for free)! iii. Journals Committee The Journals Committee (JC) is composed of Louis Deaett (for IMAGE), Froilán Dopico (for ELA), Chi-Kwong Li, Beatrice Meini (Chair), and Peter Šemrl. Froilán Dopico reported for the committee. The new ILAS Bylaws approved on April 2, 2021, were implemented. In details, concerning ELA, they imply that 1. Editors term is from January 1st, YEAR to December 31, YEAR+2. Four months before the term ends, the Editor-in-Chief (EiC) proposes to the JC renewal/termination. 2. Editors who started the service before the new ILAS Bylaws were asked if they were willing to continue the service till December 31, 2023. All accepted except one. 3. The annual report is submitted each year by the EiC in February to the Chair of the JC. Concerning ELA EiC: 1. Michael Tsatsomeros finished his second term as EiC on February 28, 2022 and now he is an Advisory Editor. President Szyld initiated a round of applause in recognition of Michael Tsatsomeros’s dedicated service to ELA and ILAS. Froilán Dopico emphasized that the services of Michael Tsatsomeros to ELA started at least in 2003 as Associate Managing Editor and sincerely thanked Michael for his great work for ELA. 2. Froilan Dopico is now the only EiC. The JC Chair (Beatrice Meini) has the credentials to act as EiC in case it is needed. The JC is working to raise the quality of ELA to high standards. In this line, the JC plans to advertise ELA to attract good authors (at ILAS endorsed conferences, in IMAGE...), and to invite survey papers from selected authors and to discuss other proposals. On December 2023 most of the ELA Editors will finish their term, a renewal is planned. It will be organized by the EiC and the JC. Suggestions of new editors from the Editorial Board of ELA will be considered. Concerning IMAGE, some editors are finishing their term, a renewal of the editorial board is planned; a Book Reviews editor would be advisable. An online meeting of the ILAS JC will be scheduled in the Fall iv. Report on the Electronic Journal of Linear Algebra The EiC of ELA, Froilán Dopico, started by recalling that ELA’s primary goals are to publish high-quality papers that support and catalyze linear algebra research and to reach prompt decisions on submissions. The EiC remarked that the Editorial Board’s efforts to raise the quality of papers that appear in ELA continue, as are the efforts to speed up the handling of submissions. Next the EiC reported on the following data of the year 2021: 1- ELA received 234 new submissions of which: 7 are still under review (as of 06/20/2022), 31 are already accepted or published, 162 were rejected outright by the EICs, i.e., without sending them to reviewers (often in collaboration with Advisory and Associate Editors), and 34 were rejected after review. 2- This amounts to a 69.2 % of outright rejections and 83.8 % of total rejections. 3- These data are like those of 2020. The EiC presented detailed data on rankings and impact factors taken from the Journal Citations Reports (JCR)-Clarivate (2020 edition) on ELA and, for the sake of comparison, on other linear algebra related journals. These journals were LAA, LAMA, SIMAX and Operators & Matrices. The EiC concluded from these and other data that ELA is ranked at a level comparable to Operators & Matrices and Special Matrices, and clearly below SIMAX, LAMA and LAA. With respect to the evolution of ELA’s Impact Factor, the EiC emphasized that a clear improvement was observed in the last four years (2017-20) with respect to the four previous ones (2013-16). Except for the year 2017, ELA is ranked in the third quartile (Q3) in the category Mathematics of JCR since 2013 and the percentile in the category has not improved despite the improvement in the Impact Factor. An effort is needed to improve the quartile of ELA, which is very relevant to several evaluation procedures (research grant proposals, faculty hiring, etc.) in Europe. It would be desirable to reach a level closer to LAA and LAMA in terms of impact factor and percentile, since these two journals have very similar scopes to ELA. The EiC emphasized that a priority of ELA for the next years is to attract greater participation in the content of ELA by ILAS members, since this participation is currently very limited. The EiC strongly encouraged the people in the audience to submit good papers to ELA since it is the research journal of ILAS. Finally, the EiC sincerely thanked all the editors of ELA, all the referees of ELA, all the authors of ELA, and the librarians of the University of Wyoming (hosting ELA) for making ELA possible. Franklin Kenter commented that according to the information in the web, ELA was Q2 not Q3 in the category “Algebra and Number Theory”. The EiC explained that this is the ranking provided by Scopus (not by JCR) and that the number of journals in this category is small (around 100). Franklin Kenter commented that, in his opinion, ILAS should not be worried by the JCR ranking since ELA is doing well with respect to the journals in the “Algebra and Number Theory” category of Scopus. The EiC remarked that, in his opinion, the fact that other linear algebra-oriented journals, as LAA, LAMA and SIMAX, are highly ranked in JCR indicates that the linear algebra community is doing very well in general terms and that ELA should be at the same level of these journals, since they have similar scopes, and at the level of the linear algebra community. Moreover, the EiC emphasized again that ELA is the journal of ILAS and that the reputation of ELA can be seen as an indicator of the reputation of ILAS, which is another reason for improving ELA’s reputation and rankings. Richard Hollister expressed concerns about whether young researchers without permanent positions should submit papers to ELA since the reputation of the journals has an influence in hiring processes. Leslie Hogben commented that the main idea of ELA’s EiC is to attract papers from established researchers in the community. The EiC thanked Leslie Hogben for the clear and adequate remark. v. Report on IMAGE The Editor in Chief of IMAGE, Louis Deaett, started by reporting that IMAGE published a significant volume of content in the three issues from Spring 2021 to Spring 2022. Google web analytics indicated that IMAGE was driving a significant portion of traffic to the ILAS web site during that period. Louis Deaett emphasized that one priority for the next year is to work to ensure that Google is properly indexing individual articles and other pieces of content in IMAGE. Right now, this seems not to be happening, and it is imperative that this is fixed. IMAGE content not being discoverable via Google is a serious problem that hampers the visibility of IMAGE and, by extension, of ILAS. As part of a related initiative, an index of individual articles/interviews/book reviews/etc. should be compiled for the ILAS web site. Louis Deaett presented other plans for IMAGE, which included renewing editorial positions (especially for articles and book reviews) and possibly creating new positions, e.g., for news items. Other planned initiatives included highlighting more mini-symposia related to linear algebra that occur within other conferences and introducing a brief interview Q&A feature to highlight a new or early-career member of ILAS with each issue. A revival of the History of Linear Algebra section may also be considered. F. Transaction of Other Business i. Future ILAS meetings Report by the Vice-President for Conferences, Raf Vandebril Raf Vandebril presented an overview of the ILAS Conferences in the past and future few years. The ILAS 2020 Conference at Galway had to be unfortunately cancelled due to the COVID pandemic and after some discussions it was moved to 2022 to guarantee as much as possible its celebration. This movement also affected the next ILAS Conference originally planned in Madrid for 2022, which will be held in 2023. Vice-President Vandebril thanked the organizers of the Madrid Conference for their flexibility for moving the conference. In 2021 an ILAS embedded conference was held inside the SIAG/LA Applied Linear Algebra Conference, originally to be held in person in New Orleans, but finally held totally virtual, again due to the COVID pandemic. In 2022 the first JMM with ILAS as partner was held, with Pauline van den Driessche as ILAS-speaker and four special ILAS sessions. This meeting was planned in person, but finally was held totally virtual again due to the COVID pandemic. In 2022, the ILAS Conference at Galway was being held at the time of this business meeting. Vice-President Vandebril thanked very much the organizers for their excellent work and, in particular, the Co-Chair of the Local Organizing Committee, Rachel Quinlan, who could not attend in person during the first four days of the conference due to COVID. Vice-President Vandebril initiated a round of applause in recognition of the local organizers of the ILAS Conference at Galway. In 2023 the second JMM with ILAS as partner will be held, with Apoorva Khare as ILAS-speaker, and again four special ILAS sessions. In 2023, the 25th ILAS Conference will be held in Madrid and the organization is progressing well. In 2024, the SIAG/LA Applied Linear Algebra Conference will be held but the location is not yet confirmed. Raf Vandebril informed that ILAS is soliciting proposals for organizing the 2025 and 2026 ILAS Conferences and encouraged the people in the audience to contact him with proposals. Presentation of the 2023 ILAS Conference at Madrid by Fernando De Terán (Chair of the Organizing and Scientific Committees) Fernando De Terán started by showing some pictures of the venue, the School of Forest Engineers of Universidad Politécnica de Madrid, which is a very nice building surrounded by trees and green areas. Next, he listed the members of the organizing and scientific committees and commented that the web page of the conference is already working. The registration fees will be similar to those of the ILAS 2022 Conference at Galway and some relevant dates (expected) will be: (1) September 2022: call for contributed Minisymposia; (2) December 2022: call for contributed talks and posters; and (3) February 2023: call for registration and abstract submission. Fernando De Terán informed that the plenary speakers were being selected and that the next immediate tasks were the selection of the invited Minisymposia and the complete development of the webpage. President Szyld asked about hotels in Madrid. Fernando De Terán answered that Madrid is a big city with many hotels and that the organization is working for recommending some of them in the webpage. ii. Any other business President Szyld asked if somebody wanted to discuss any other issue. No other issues were discussed. G. Adjournment President Szyld thanked the committees' chairs or their representatives for their presentations, which illustrate the breadth and depth of the Society's activities. He also commented on the breadth of the plenary talks at the meeting and commended the Scientific Committee for that. Finally, he thanked the Local organizers for a great meeting. President Szyld adjourned the meeting at 18:05 GMT+1 Respectfully submitted by Froilán Dopico, Vice-President of ILAS.

2023 May 22 ILAS-NET Message No. 2482 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B. Szyld SUBJECT: ILAS Lectures at Non-ILAS Conferences and General Support for Non-ILAS Events 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 financial 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. 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 2023 for receipt of proposals for sponsorship of ILAS Lectures at non-ILAS meetings and for general support of conferences taking place in 2024. 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. A statement whether the conference will adhere to the ILAS Welcoming and Inclusiveness Statement should be included in the proposal. Further details on the guidelines for proposals can be found at the following link: https://ilasic.org/non-ilas-guidelines/. (Note that the guidelines have been changed from previous years.) 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/conferences/#ilas-endorsed-meetings. (Note that the guidelines have been changed from previous years.) Daniel B. Szyld (he/him/his) ILAS President

2023 May 04 ILAS-NET Message No. 2481 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B. Szyld and Froilán Dopico SUBJECT: ILAS President and Vice-President Annual Report (1 May 2023) ILAS President/Vice-President Annual Report: May 1, 2023 Respectfully submitted by Daniel B. Szyld, ILAS President, szyld@temple.edu, and Froilán M. Dopico, ILAS Vice-President, dopico@math.uc3m.es. The past year has been another momentous year for ILAS. Among the highlights are that the ILAS Community met again in person after the hard times of the COVID pandemic in the 24th ILAS Conference held in Galway, Ireland (June 20-24, 2022); the first ILAS Richard A. Brualdi Early Career Prize was awarded to Michael Tait; the second participation of ILAS as a partner in the Joint Mathematics Meetings (JMM) 2023, the first time as partners in person; and a new childcare grant program for ILAS members who are parents of young children so as to make it easier to attend an ILAS Conference. 1. Board-approved actions since the last report include: • The Board approved a new dues structure for the Society. It was decided to maintain the previous dues of \$40 per year for the "standard" membership. A new category of Early Career Member was established and defined as a person within five years of receiving a PhD degree. The dues for Early Career members are at 50% of the standard membership, that is, \$20 per year. As in the past, any member can request that their dues be waived for financial hardship. Current student members continue to enjoy free membership. This dues structure is reflected in the ILAS website at https://ilasic.org/join-ilas/. Lifetime membership continues to be available. Paying for more than one year at a time is also possible. • The Board approved new reimbursement guidelines for the travel and accommodation expenses for ILAS Executive Officers, other officers, and editors in Conferences. These guidelines state clearly in one document the set of common practices followed so far by ILAS on this issue. • The Board approved on October 20, 2022, some revisions of the ILAS Bylaws with the main goal of avoiding the possibility of a conflict of interest in the appointment of the nominating committee members. The new Bylaws can be found at ILAS Website. • The Board approved that the 26th Conference of the International Linear Algebra Society will be held in Kaohsiung, Taiwan, June 23-27, 2025, with Jephian C.-H. Lin (National Sun Yat-sen University) and Matthew M. Lin (National Cheng Kung University) as main organizers. • The Board approved an increase of \$50 for the institutional membership rates. This means an increase from $200 to $250 for the fees of silver institutional members and from $350 to $400 for the fees of gold institutional members. • The Board approved a grant childcare program for ILAS members who are parents of young children to make it easier to attend an ILAS Conference. The grants up to the amount of $500 can be used to pay for childcare either at the conference city, or the home city of the ILAS member. In the latter case, it is for any additional childcare expenses incurred because the ILAS member is attending the conference. The grant can also be used to subsidize travel of a person who would take care of the child during the conference. Complete details can be found at https://ilasic.org/childcare-grants/. 2. Other news: • The inaugural ILAS Richard A. Brualdi Early Career Prize was awarded to Michael Tait (Villanova University, USA) “for outstanding contributions to spectral theory of graphs, developing new techniques, and settling several long-standing open problems in that area." Michael Tait will present the prize lecture at the 25th ILAS Conference in June 2023 in Madrid (Spain). The selection committee consisted of: Marina Arav, Volker Mehrmann, Shmuel Friedland (chair), and Daniel B. Szyld (ILAS President, ex officio). • The 2023 ILAS Taussky–Todd Prize was awarded to Stefan Güttel (University of Manchester, UK) “for deep and impactful work on rational Krylov methods for nonlinear eigenvalue problems and matrix functions, in all aspects: analysis, software development, and applications." Stefan Güttel will present the prize lecture at the 25th ILAS Conference in June 2023 in Madrid (Spain). The selection committee consisted of Nair Abreu, Ilse Ipsen (chair), Joseph Landsberg, Pauline van den Driessche, and Daniel B. Szyld (ILAS President, ex officio). The Joint Mathematics Meetings 2023 (JMM 2023, an ILAS partner conference) was held in Boston, January 4-7, 2023. The ILAS address was given by Apoorva Khare (Indian Institute of Science, Bangalore) with title "Analysis and applications of Schur polynomials". There were four ILAS Special Sessions: (1) Matrix Analysis and Applications (organized by Hugo Woerdeman and Edward Poon); (2) Matrices and Operators (organized by Mohsen Aliabadi, Tin-Yau Tam, and Pan-Shun Lau); (3) The Inverse Eigenvalue Problem for a Graph and Zero Forcing (jointly presented with AIM (American Institute of Mathematics) and organized by Mary Flagg and Bryan A Curtis); and (4) Innovative and Effective Ways to Teach Linear Algebra (organized by David M. Strong, Gilbert Strang, Sepideh Stewart, and Megan Wawro). • The Executive Board accepted the recommendation of the JMM Committee that Stephan Ramon Garcia from Pomona College (California) be the ILAS Lecturer at the Joint Mathematics Meetings 2024, to be held in San Francisco, January 3-6, 2024. In addition to this ILAS Lecture, there will be five ILAS Special Sessions scheduled at JMM 2024. The JMM committee consisted of Nair Abreu, Ilse Ipsen (chair), Joseph Landsberg, Pauline van den Driessche, and Daniel B. Szyld (ILAS President, ex officio). • The Israel Gohberg ILAS-IWOTA Lecture Selection Committee selected the ILAS Member Mark Embree as Israel Gohberg Lecturer in the International Workshop on Operator Theory and its Applications (IWOTA) to be held at the University of Kent, UK, August 12-16, 2024. The selection committee consisted of Jussi Behrndt (IWOTA), Kelley Bickel (ILAS), Micheal Dritschel (IWOTA) and Ilya Spitkovsky (ILAS). More information on this lecture series can be found at https://ilasic.org/special-lectures-support/. • The 24th ILAS Conference at Galway (Ireland, June 20-24, 2022) was held in person. It was originally scheduled for 2020 but it had to be postponed due to the COVID pandemic. Despite the uncertainties caused by the pandemic, the conference was very successful and included 260 registered participants, a total of 256 talks and posters (6 posters and 250 talks). There were 10 plenary talks and 40 contributed talks, the rest of the talks were in 22 minisymposia.

2023 April 19 ILAS-NET Message No. 2479 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B. Szyld SUBJECT: Childcare Grants and Other Initiatives ILAS is providing grants to ILAS members who are parents of young children so as to make it easier to attend an ILAS Conference. The grants up to the amount of \$500 can be used to pay for childcare either at the conference city, or the home city of the ILAS member. In the latter case, it is for any additional childcare expenses incurred because the ILAS member is attending the conference. The grant can also be used to subsidize the travel of a person who would take care of the child during the conference. Applications need to be sent at least two months in advance of the conference dates indicating: • Name of the ILAS member • Name of the child/ren and their ages • Expected budget and type of expense Applications can be sent directly to the ILAS President. The ILAS President will communicate the decision to each applicant no later than one month after the application is received. Reimbursements will be sent to the applicant after the applicant has attended the conference and once appropriate receipts for up to $500 have been submitted to the ILAS Secretary/Treasurer. For the ILAS Conference in Madrid, 12–16 June, 2023, the deadline for applications is May 1st, 2023. Other initiatives that ILAS is putting into place include: • Aiming to have a break every two hours or so during the ILAS conferences to allow parents see their children if necessary. • Invited speakers with young children could stay in apartments and not necessarily in a hotel. • If the caretaker/companion is traveling with the parent, ILAS will facilitate free registration to the conference if such caretaker wishes to attend a few lectures. • The ILAS President will aim to put in contact parents of young children in case they want to coordinate activities. • Children will be welcomed at the coffee breaks, excursions, or other social activities.

2023 April 12 ILAS-NET Message No. 2476 CONTRIBUTED ANNOUNCEMENT FROM: Christine Andrews-Larson SUBJECT: Call for Abstracts—MAA MathFest 2023 Dear Colleagues: Saturday April 30 at 11:59 PM EDT is the deadline to submit an abstract to talk in a themed contributed paper session at MAA MathFest in Tampa, Florida August 2–5, 2023. Please consider submitting a talk on your recent scholarly work. Link for more information about Mathfest, to register (Early Bird rates end April 15, Advance rates run through June 30), or to submit an abstract: MAA MathFest 2023. We especially invite submissions for our themed contributed paper session: Linear Algebra: Modern Applications and Computation This session invites examples of modern applications of linear algebra and computation successfully incorporated in undergraduate linear algebra courses with evidence of that success in terms of student learning, student engagement, student persistence in STEM, etc. and/or recent research in linear algebra accessible to undergraduates, for example topics for undergraduate research projects, course projects, or illustrative examples for a course. Organizers: Suzanne Dorée, Augsburg University (doree@augsburg.edu) Christine Andrews-Larson, Florida State University David Austin, Grand Valley State University Monika Kiss, St. Leo's University Some additional advice is below. I hope to see many of you in Tampa this summer! Christy Andrews-Larson New to MAA Themed Contributed Paper Sessions? Logistics and Expectations: Each themed contributed paper session is a sequence of 15 minute talks on topics of general interest to MAA members and meeting participants (i.e. not highly specialized talks for collaborators). To give a talk, you first need to submit an abstract by the deadline. Next the organizers consider each abstract to evaluate its fit with the session description. Proposers are notified of the decision fairly quickly. In practice, most abstracts are accepted. You must register for the meetings and be present in person to present. Each talk is limited to one speaker and any one person may only give one talk total across the contributed paper sessions. Some advice from organizer Su Dorée in preparing the abstract and talk: We are excited to hear about the work you are doing to modernize the Linear Algebra curriculum at the undergraduate level or work you are doing in Linear Algebra research that lends itself to use in undergraduate courses. Talks should include at least one example of the mathematics itself that might spark the interest of audience members enough to encourage them to modernize their own courses. Be sure the abstract addresses how your work connects to undergraduates AND applications or computations in Linear Algebra. While a little institutional context is important, the bulk of your talk should be what you did that was new or innovative, why you did it, how well it worked to implement this idea in the curriculum (or how someone might do that), and some lessons learned. The audience will especially perk up at specific ideas that they can use in their own curriculum. Rather than list everything you did, consider selecting a succulent example or two to whet our appetite and then offer a way for folks to contact you, for example to see your materials, learn more about your pedagogy, or see the specific results of assessment. In addressing assessment or research on learning Linear Algebra, the audience is going to be most interested in what your research questions were and how you actually collected data, so that we can potentially replicate those methods ourselves. Limit data to a few key numbers or quotes as much of the audience is likely to be math professors, not education researchers, administrators, or funding agencies.

2023 January 24 ILAS-NET Message No. 2460 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B. Szyld SUBJECT: ILAS Lectures at Non-ILAS Conferences and General Support at Non-ILAS Events 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 financial 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. 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 2023 for receipt of proposals for sponsorship of ILAS Lectures at non-ILAS meetings and for general support of conferences taking place in 2024. 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. A statement whether the conference will adhere to the ILAS Welcoming and Inclusiveness Statement should be included in the proposal. 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/conferences/#ilas-endorsed-meetings.

2023 January 19 ILAS-NET Message No. 2459 CONTRIBUTED ANNOUNCEMENT FROM: Andrii Dmytryshyn SUBJECT: Postdoctoral position at Örebro University Örebro University and the School of Science and Technology are looking for a postdoc in mathematics (linear algebra, optimization, ...). The project is about data completion problem for motion capture systems. Motion-capture systems are used for investigating and improving various mechanical processes. There are many ways of tracking motion using such systems. In the project we focus on the problems associated with the usage of passive markers and video recording. This type of tracking requires that the markers are visible in the video which is not always the case. Therefore, tracking the motions may become problematic or even impossible and, therefore, a sophisticated method for completing the data from the missing markers is needed. If you are interested in this position send your CV to andrii.dmytryshyn@oru.se as soon as possible.

2023 January 19 ILAS-NET Message No. 2458 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B.

2023 January 12                                              ILAS-NET Message No. 2455 CONTRIBUTED ANNOUNCEMENT FROM: Daniel B. Szyld SUBJECT: JMM2023 Report & Call for Special Sessions for JMM 2024 Dear ILAS members and friends of ILAS: We just concluded the activities of the Joint Mathematics Meetings in Boston. As you know, ILAS is a partner member of the JMM, and this was the first time we attended in-person in this capacity. It was nice to see so many ILAS people at the ILAS address, given by Apoorva Khare, and at the multiple ILAS Special Sessions. Apoorva Khare's talk was titled "Analysis and applications of Schur polynomials". In his lecture, Prof. Khare presented several results involving Schur polynomials, viewed as functions on the positive orthant. A true tour de force involving material studied since the XVIII Century, and others from more recent times. This talk was taped. So, in a month or so, it will appear on the AMS YouTube channel. Apoorva was publicly recognized for his lecture at the JMM Prize Ceremony and awarded a framed certificate (official pictures coming soon). The four special sessions were lively and well-attended. They were: • Matrix Analysis and Applications (organized by  Hugo Woerdeman and Edward Poon), • Matrices and Operators (Organized by Mohsen Aliabadi, Tin-Yau Tam, and Pan-Shun Lau),  • The Inverse Eigenvalue Problem for a Graph and Zero Forcing (jointly presented with AIM and organized by Mary Flagg and Bryan A Curtis), and  • Innovative and Effective Ways to Teach Linear Algebra (organized by David M. Strong, Gil Strang, Sepideh Stewart, and Megan Wawro). It is not too early to start thinking of organizing an ILAS Special Session for the JMM 2024 to be held in early January in San Francisco. Please consider doing so and by writing to Raf Vandebril (raf.vandebril@kuleuven.be), VP for Conferences. Daniel B. Szyld ILAS President
