Exceptional supercuspidal representations in small residue characteristic

Representation Theory 2026-03-23 v2 Number Theory

Abstract

In this paper, in residue characteristic 2 and 3, we extend the construction of epipelagic representations of Reeder--Yu to produce new supercuspidals of higher depth, building on work of Gastineau. In particular, we produce examples of epipelagic representations that do not arise from the construction of Reeder--Yu.
