Iwahori's Question for Affine Hecke Algebras
Shoji, Toshiaki · Xi, Nanhua
Original · EN
In this paper we show that an affine Hecke algebra Hq over complex numbers field with parameter q≠ 1 is not isomorphic to the group algebra over complex numbers field of the corresponding extend affine Weyl group if the corresponding root system has no factors of type A₁ and the order of q is different from 11 and 13 if the root system has factors of type E₈.
