Yesterday was the last day of the 2024 ECM in Sevilla! In the morning, IHES Permanent Professor Maxim Kontsevich gave a Plenary Lecture on the Generalized Riemann-Hilbert correspondence, wall-crossing, and resurgence. Just after him, Anna Wienhard, Director of the Max Planck Institute for Mathematics in the Sciences, who was introduced by former IHES Director Jean-Pierre Bourguignon, reported on recent advances in Anosov representations and higher Teichmüller spaces. In her talk, she notably mentioned the work of IHES Postdoc Sami Douba, IHES PhD student Balthazar Fléchelles, and IHES CNRS - Centre national de la recherche scientifique Research Director Fanny Kassel. IHES, along with all of its partners at the Math in France stand, wishes to thank and congratulate Juan González-Meneses López, Isabel Fernandez (Universidad de Sevilla), and the whole organizing committee for hosting an inspiring conference in the wonderful town of Sevilla!

There was a lot going on at the ECM in Sevilla today! In the morning, Etienne Ghys (Académie des sciences, École normale supérieure de Lyon) delivered the Hirzebruch lecture, where he delved into the question of what constitutes a great theorem. He then tested his criteria on the recent proof of the simplicity conjecture by Dan Cristofaro-Gardiner (University of Maryland), Vincent Humilière (Sorbonne Université), and Sobhan Seyfaddini (CNRS - Centre national de la recherche scientifique, Université Paris-Saclay). https://lnkd.in/giCGnfcN During the afternoon coffee break, Maxim Kontsevich and ECM Prize Winner Danylo Radchenko (CNRS - Centre national de la recherche scientifique, Université de Lille) stopped by the Math in France booth. In the “Mathematical Information in the Digital Age of Science” contributed session, Jean-Pierre Bourguignon spoke on scientific publishing and the recommendations of the Committee on Electronic Information and Communication (CEIC) of the International Mathematical Union. https://lnkd.in/gFJwSb7s The day ended with yet another talk by IHES postdoc Edmund Heng at the Computational Group Theory mini-symposium, where he presented joint work with Ben Elias (University of Oregon) on embeddings of Coxeter groups. Together, they discovered a new proof of results previously known to Anatole Castella, John Crisp, and Bernhard Mühlherr (Justus-Liebig-Universität Giessen). https://lnkd.in/geJqsrXz CIMPA (Centre International de Mathématiques Pures et Appliquées) Centre International de Rencontres Mathématiques - Cirm CNRS - Centre national de la recherche scientifique Fondation Sciences Mathématiques de Paris

This week, Hugo Duminil-Copin (IHES & Université de Genève) is participating in the astrophysics summer school for undergraduates of Université Paris-Saclay organized by Martine Chane-Yook, Hervé Dole and Cateline Lantz at the Observatoire de Haute-Provence!

Another warm and sunny day ends at the ECM in Sevilla! Today, Yilin Wang, Junior Professor at IHES, and Edmund Heng, a Postdoc at IHES, had the privilege to present their work at the congress. In her invited lecture, Yilin explained her work at the crossroads of Schramm-Loewner evolution, Kähler geometry on the universal Teichmüller space, and hyperbolic 3-manifolds. In his talk in the algebra session, Edmund discussed his recent paper with Hannah Dell (The University of Edinburgh) and Anthony Licata (The Australian National University), where they generalize a result of Macrì (Université Paris-Saclay), Mehrotra (Chennai Mathematical Institute), and Stellari (Università degli Studi di Milano) on Bridgeland stability conditions in fusion categories. At the Math in France booth, we are now finally in the company of our colleagues from Centre International de Rencontres Mathématiques - Cirm ! Former Publications Mathématiques de l'IHES Editor-in-Chief Etienne Ghys (Académie des sciences, École normale supérieure de Lyon) also stopped by before his Hirzebruch lecture on Thursday!

IHES is participating in this year’s European Congress of Mathematics in Sevilla! Together with, CIMPA (Centre International de Mathématiques Pures et Appliquées), Centre International de Rencontres Mathématiques - Cirm , INSMI (CNRS - Centre national de la recherche scientifique) and Fondation Sciences Mathématiques de Paris, we have a common "Math in France" booth. Come see us if you are around ! Today, the congress started with the opening ceremony and the announcement of the EMS prize winners. Warm congratulations to all the laureates, particularly Maria Colombo (EPFL), who visited IHES this year to give a series of Hadamard Lectures of the FONDATION MATHEMATIQUE JACQUES HADAMARD (FMJH) on Flows of Irregular Vector Fields in Fluid Dynamics. After the first set of lectures in the afternoon, participants had the chance to visit the famous Alcázar castle in the old town of Sevilla. Stay tuned for more news from ECM...

IHES is celebrating the five-year anniversary of the Gretchen and Barry Mazur Chair! https://lnkd.in/eJECWH6w This Chair, reserved for a mathematician visiting IHES, is endowed by generous gifts from Margaret and William R. Hearst III, made to Friends of IHES, the partner organization of IHES in the United States. For the anniversary of the Chair, IHES has made Oliver Ralfe’s intimate documentary, “Barry Mazur and the Infinite Cheese of Knowledge,” available on its YouTube channel. The film notably features Curtis T. McMullen, Fields Medalist and the next holder of the Gretchen and Barry Mazur Chair. https://lnkd.in/enxUDA4B Sheep Street Films Harvard University

France Culture has just released an excellent series of podcasts (in French) by Marie Durrieu on the life and work of Alexander Grothendieck who was a Permanent Professor in Mathematics at IHES from 1958 to 1970. Episode 2, in particular, touches upon his revolutionary work in algebraic geometry carried out at the Institute. Besides an audio archive of Léon Motchane, the Institute's founder and first Director, it also includes testimonies by Jean-Pierre Bourguignon, Pierre Deligne, Michel Demazure, Luc Illusie, Laurent Lafforgue and Emmanuel Ullmo amongst many others. https://lnkd.in/eDmAgf4b

Following the scientific breakfast organized in July 2023 with Thibault Damour, theoretical physicist and Professor Emeritus at IHES, the Institute returned to the British capital in June 2024. IHES gathered its London community on June 19th for a scientific breakfast with Yilin Wang Wang, junior professor of mathematics at IHES since 2022, introduced by Rama CONT. This event was organized with the support of the Department of Higher Education, Research, and Innovation of the French Embassy in the United Kingdom for the second year in a row. https://lnkd.in/eHj-G2nz
