Character sheaves on loop Lie algebras: polar partition

Representation Theory 2025-06-18 v1 Number Theory

Abstract

In this paper we propose a partition of loop Lie algebras into invariant sets parametrized by polar data. Our polar partition is motivated by J-K. Yu's construction of supercuspidal representations and leads to a conjectural construction of character sheaves on loop Lie algebras.
