On Wednesday, November 6, 2024, the director of CRM-CNRS met with the Vice-Rector for Research, Discovery, Creation, and Innovation of the University of Montreal, Marie-Josée Hébert.

The meeting was an opportunity to thank the University of Montreal for hosting CRM-CNRS in its facilities and to express the importance of the investment from CNRS and the Fonds de recherche du Québec for Franco-Quebec cooperation in mathematics.

The main tools of this cooperation were presented:

Starting November 1, 2024, and for seven months, the CRM-CNRS welcomes Pierre Baumann

Pierre BAUMANN

Researcher, CNRS

11/01/2024 – 06/30/2025

Pierre Baumann is a CNRS researcher at the Institute for Advanced Mathematical Research in Strasbourg. His work focuses on representations of Lie groups and algebras, at the intersection of algebra, combinatorics, and geometry. In his mathematical garden one can find various species of preprojective algebras, affine Grassmannian varieties, affine root systems, crystal polytopes and paths, cluster structures, and the ever-challenging perverse sheaves. His stay at the CRM will allow him to pursue long-standing collaborations with colleagues at LACIM (UQAM).

On October 28, 2024, the inaugural conference of the Franco-Uruguayan Institute of Mathematics and Interactions (Ifumi) was held in Montevideo (Uruguay). Established fifteen years ago, the laboratory has acquired the status of an international research laboratory of the CNRS (IRL).

Welcome to this sixth international research laboratory of the CNRS (IRL) in mathematics on the American continent!

The CRM-CNRS is holding the general assembly of its scientific staff on October 4, 2024, at 10 a.m. in room 5374-1.

Starting September 1, 2024, the CRM-CNRS IRL will host nine scientists for long-term stays.

Nicolas BOUSQUET

Researcher, CNRS

09/01/2024 – 08/31/2025

After earning a PhD in fundamental computer science in 2013 at LIRMM in Montpellier, Nicolas Bousquet joined CNRS in 2016 as a researcher, first at the G-SCOP laboratory in Grenoble and since 2020 at the LIRIS laboratory in Lyon.

The core of his research focuses on structural theory and graph algorithms. But his interests extend beyond these topics: game theory, combinatorics… In recent years, he has focused on reconfiguration problems, which aim to determine conditions that guarantee the existence of transformations between problem solutions. He also works on distributed algorithms and local certification.

Dear colleagues at the CRM, dear colleagues at the IRL,

My term as director of the IRL (or UMI) comes to an end after an additional year, and Emmanuel Royer will take over on September 1. Emmanuel is a professor at Université Clermont-Auvergne, where he headed the Blaise Pascal Mathematics Laboratory from 2014 to 2018 before serving as deputy scientific director of the CNRS National Institute for Mathematical Sciences and their Interactions (INSMI) from 2018 to 2023. Since his PhD, prepared under Étienne Fouvry and Philippe Michel and defended in 2001, he has worked in number theory, focusing in particular on modular forms and related functions.
