Finite-dimensional quotients of Hecke algebras

Ivan Losev

Vol. 9 (2015), No. 2, 493–502

Let W be a complex reflection group. We prove that there is a maximal finite-dimensional quotient of the Hecke algebra q(W) of W, and that the dimension of this quotient coincides with |W|. This is a weak version of a 1998 Broué–Malle–Rouquier conjecture. The proof is based on the categories O for rational Cherednik algebras.
