Hecke algebras, representations and combinatorics

Université de Tours, 7-9 July 2026

A conference to celebrate the life and work of Jérémie Guilhot (1980–2025), highlighting the areas of mathematics where he made profound contributions: combinatorics of root systems and Coxeter groups, representations of Hecke algebras and Kazhdan-Lusztig theory, combinatorial Lie theory, and random walks.
