Matrices filled by variables, from posets to Coxeter groups, and beyond

By Maxim Kontsevich

Appears in collection : Combinatorics and Arithmetic for Physics - 2024

Last year at CAP2023 I gave a talk about a class of matrices filled by variables, whose eigenvalues are linear forms in the variables. The construction was based on finite posets. I'll speak about a generalization to convex sets in general reflection groups, and even to the case where there is no group at all.
