Unipotent representations: changing q to -q, II

Representation Theory 2025-10-17 v2

Abstract

Consider a Chevalley group over a finite field F_q such that the longest element in the Weyl group is central. In this paper we study the effect of changing q to -q in the polynomials which give the character values of unipotent representations of our group at semisimple elements.
