Sharpness versus bluntness in affine Weyl groups

Representation Theory 2023-11-07 v3

Abstract

We give an explanation of the bijection between geometric and arithmetic diagrams attached to supercuspidal unipotent representations of a simple p-adic group which is based purely on algebra. The second version contains much additional material compared to the first version.
