Ordinary parts and local-global compatibility at $\ell=p$

Number Theory 2024-10-29 v2 Representation Theory

Abstract

We prove local-global compatibility results at =p\ell=p for the torsion automorphic Galois representations constructed by Scholze, generalising the work of Caraiani--Newton. In particular, we verify, up to a nilpotent ideal, the local-global compatibility conjecture at =p\ell=p of Gee--Newton in the case of imaginary CM fields under some technical assumptions. The key new ingredient is a local-global compatibility result for QQ-ordinary self-dual automorphic representations for arbitrary parabolic subgroups.
