The Mathematical Council of the Americas is a network for professional mathematical societies and research institutes based in the Americas, dedicated to promoting the development of Mathematics, in all its aspects, across the continents.  As a hemispheric collaborative effort, special attention is given to cooperating with UMALCA—the Mathematical Union for Latin America and the Caribbean.  The Mathematical Council aims to highlight the excellence of mathematical achievements in the Americas within the context of the international arena and to foster the scientific integration of all mathematical communities on the continent.  Both the Mathematical Council of the Americas (MCofA) and UMALCA are Affiliate Members of the IMU.

The principal vehicle by which the Math Council advances its goals is through the now well-established quadrennial Mathematical Congress of the Americas (MCA).  The first MCA was hosted by the Centro de lnvestigación en Matemáticas (CIMAT) in Guanajuato, Mexico, August 5–9, 2013, followed by the Montreal MCA, July 24–27, 2017, hosted by the Canadian Mathematical Society.  The 2021 MCA was sponsored by the Department of Mathematics at the University of Buenos Aires.  Due to the COVID 19 pandemic, it was held virtually from July 9 to July 23.

The Fourth Mathematical Congress of the Americas (MCA 2025) was recently held in Miami, Florida, at the Intercontinental Hotel Miami, July 21–25, 2025.  It was hosted by the Department of Mathematics at the University of Miami.  This marks the first time the MCA was held in the United States.

Located in the heart of booming downtown Miami, with commanding views of the Atlantic Ocean, Biscayne Bay and the Port of Miami, the Intercontinental proved to be a splendid venue for MCA 2025.  The Intercontinental is an ideally appointed facility, with 653 guest rooms and over 100,000 square feet of meeting space spread over 35 meeting rooms, which was fully utilized to execute the congress.  The diligent and energetic hotel staff worked closely with our excellent management team from the Sight on Site Group to create a conducive and welcoming atmosphere.

We convened almost 950 mathematicians from across the Americas and beyond to explore bold ideas, advance research, and foster collaboration across borders.  Over the course of the week, MCA 2025 featured 5 Plenary Sessions, where world-renowned speakers shared frontier research and unifying themes in modern mathematics, and 18 Invited Talks, offering deep dives across diverse subfields.  These headline talks went hand in hand with a vibrant scientific program with over 750 presentations organized into 66 special session topics, reflecting the inspiring range of mathematical research taking place across the hemispheric mathematical community.

We celebrated excellence in mathematical research and community across the hemisphere through the 2025 MCA Awards Ceremony, recognizing outstanding contributions in three categories.  First, the Americas Prize is awarded to an individual or a group in recognition of their work to enhance collaboration and the development of research that links mathematicians in several countries in the Americas.  The 2025 prize was shared by Pablo Ferrari of the University of Buenos Aires and the late Maria Soares Ruas of the University of São Paulo.  Second, Lefschetz Medals are given to two mathematicians in recognition of their excellence in research and their contributions to the development of mathematics in a country or countries in the Americas.  The recipients for 2025 are Alicia Dickenstein of the University of Buenos Aires and Tatiana Toro of the Simons Laufer Mathematical Institute and the University of Washington.  Finally, the MCA Prize is awarded to mathematicians, no more than 12-year post PhD, who either did graduate training at an institution or institutions in the Americas or currently hold a position in one or more countries of the Americas.  The recipients for 2025 are: Roger Casals, University of California at Davis, Yu Deng, University of Chicago, Javier Gómez-Serrano, Brown University, Carlo Pagano, Concordia University, and Julian Saharabudhe, University of Cambridge.  Each MCA Prize winner gave a superb presentation at the congress.

Complementing the core program were 35 poster presentations, evening events that encouraged connection and reflection, and unique opportunities for community engagement.  The week opened with the MCA 2025 Welcome Reception on Monday evening.  On Wednesday evening, we hosted a Special Public Lecture by Tadashi Tokieda, who brought mathematical wonder to a broad audience.  On Thursday evening, Tech Night spotlighted the intersection of mathematics, data, and innovation in Miami’s high-knowledge economy via a fireside chat with Tom DeBow, Chief Technology Officer of Schonfeld Strategic Advisors.  Participants got an insightful perspective in the emergence of Miami as a hub for the high-knowledge economy and an industry perspective on artificial intelligence that resonated with several excellent talks at MCA 2025.

MCA 2025 is very grateful to the sponsors who helped to make the event possible and whose funds enabled the attendance of many mathematicians from across the Americas.  We are pleased to salute (in alphabetical order) American Airlines, the American Mathematical Society, the Atlantic Association for Research in the Mathematical Sciences, the Center for Mathematical Modeling, the Centre de Recherches Mathématiques, the Fields Institute for Research in Mathematical Sciences, the Institute of the Mathematical Sciences of the Americas, the Instituto de Matemática Pura e Aplicada, the Mathematical Council of the Americas, the National Science Foundation, the Pacific Institute for the Mathematical Sciences, Santander Bank, Schonfeld Strategic Advisors, the Simons Foundation, and the University of Miami.

Fraudulent publishing and citation cartels have emerged as a significant concern within our community.  Notably, in November 2023, Clarivate, the parent company of Web of Science, announced that it excluded the entire mathematical discipline from the most recent edition of its list of highly cited authors.  The rationale provided for this exclusion was as follows (see Clarivate’s blog entry by David A. Pendlebury, November 15, 2023, Highly Cited Researchers 2023: The evolution of our evaluation and selection policy to support a robust scholarly landscape):

“(Mathematics) is a highly fractionated research domain, with few individuals working on a number of specialty topics.  The average rate of publication and citation in Mathematics is relatively low, so small increases in publication and citation tend to distort the representation and analysis of the overall field.  Because of this, the field of Mathematics is more vulnerable to strategies to optimize status and rewards through publication and citation manipulation.”

Since then, the International Mathematical Union (IMU) and the International Council of Industrial and Applied Mathematics (ICIAM) have established a working group to delve deeper into the study of fraudulent publishing and citation cartels.  This working group, comprising Ilka Agricola, Lynn Heller, Wil Schilders, Moritz Schubotz, Peter Taylor, and Luis Vega, has recently authored a report on the subject and has formulated precise recommendations for policymakers and institutions, outlining strategies to foster ethical scientific practices while simultaneously detecting and addressing fraudulent conduct.

For individuals, the recommendations provide a set of possible actions to safeguard research communities from being corrupted by fraud and pure business interests.

These recommendations were formulated by the authors in close collaboration with the IMU Committee on Publishing (chaired by Ilka Agricola) and were endorsed by the Executive Committee of the IMU and the Board of the ICIAM in May/June 2025.

Please find the recommendations and report below:

• 2025 IMU-ICIAM Recommendations on Fraudulent Publishing
• 2025 IMU-ICIAM Report on Fraudulent Publishing

The report will appear in the October issue of the Notices of the American Mathematical Society.

ICMI Awardees Multimedia Online Resources Project.  The ICMI AMOR Project, initiated in 2017 by Jean-Luc Dorier, aims at building online resources reflecting highly significant and influential research in mathematics education at an international level, which could serve as a reference not only for researchers in the field, but also for educators, teachers, curriculum developers and policy makers and other agents in the field.  In particular, the project could serve as a basis for a PhD training program and induction into mathematics education research.  In this presentation you can have a quick glance at the videos in the units of the project.  You can also access a flyer and posters here and here.

Moreover, we have made our YouTube channel more accessible and with new functionalities.  At the moment the automatic translations in different languages offered by YouTube are not always very accurate but with the advisory board, we are working on making them better.  Out of 24 awardees, 7 units are completed and several are in progress.

At its Executive Committee Meeting held March 10–12, 2025, ICMI decided to set up an Advisory Board for the ICMI AMOR Project.

The roles of the Advisory Board are to:

• Establish priorities for new AMOR units to be created and help with contacting people who can design these new units.
• Help anyone who wants to start building a new AMOR unit in the project, explaining the goals and the format and interacting with this person or persons about the various design possibilities.
• Identify the ideal characteristics for each new AMOR unit to be added based on features of units that have already been designed and published.
• Offer advice and feedback on the design of a whole AMOR unit and each module in it.  This is not a formal review but instead an advisory process to help optimize the quality of the finished product.
• Take action to promote the project to new and existing audiences and to enhance its impact.  This means reviewing what is known about existing use of the AMOR units and proposing new uses and new audiences.  It also means communicating about the project and its possible uses via various media and conferences.

The members of the Advisory Board are appointed by the ICMI EC for a period of 4 years starting on April 1, 2025.

The Advisory Board is composed of a balanced mixture of persons active in the origin of AMOR and senior and junior researchers in mathematics education working and living in different parts of the world and using different theoretical tools, reflecting the possible users of the ICMI AMOR Projects.  The total number of Advisory Board members should be between 9 and 15.

Here is the list of first appointees starting on April 1, 2025:

• Michèle Artigue (France)
• Marianna Bosch Casabò (Spain)
• Nadav Ehrenfeld (USA/Israel)
• Anthony Essien (South Africa)
• Fraser Gobede (Malawi)
• Xingfeng Huang (China)
• Ruchi Sunil Kumar (India)
• Nathan Lombard (France/Switzerland)
• Daniela Pages (Uruguay)
• Anna Sfard (Israel)

The work of the Advisory Board will be chaired by Betina Duarte, who as ICMI Vice-President is in charge of the ICMI AMOR Project.

Updates on the short descriptions of the context of mathematics education in different countries.  As announced in our last newsletter, when reshaping its website, the ICMI EC has decided to replace the database project by a wider presentation of the context of Mathematics Education in every ICMI country according to the following 5 sections:

• Associations for Mathematics Education
• Research Institutions for Mathematics Education Research
• Journals for Mathematics Education Research
• Mathematics Teacher Education
• National Syllabus and Standard

At the moment, the information is accessible for the following countries: Australia, Bangladesh, Bulgaria, Costa Rica, the Czech Republic, Finland, France, Germany, India, Italy, Kenya, Latvia, the Netherlands, Norway, Malawi, Poland, Switzerland, Thailand and Uruguay.  We hope that this list will grow rapidly!
