Infinitesimal characters in arithmetic families

Number Theory 2020-12-03 v1 Representation Theory

Abstract

We associate infinitesimal characters to (twisted) families of LL-parameters and CC-parameters of pp-adic reductive groups. We use the construction to study the action of the centre of the universal enveloping algebra on the locally analytic vectors in the Hecke eigenspaces in the completed cohomology.
