On the basic representation of the double affine Hecke algebra at critical level

Representation Theory 2024-12-13 v1

Abstract

We construct the basic representation of the double affine Hecke algebra at critical level q=1q=1 associated to an irreducible reduced affine root system RR with a reduced gradient root system. For RR of untwisted type such a representation was studied by Oblomkov [O04] and further detailed by Gehles [G06] in the presence of minuscule weights.
