Potential automorphy over CM fields

Number Theory 2022-06-17 v2

Abstract

Let FF be a CM number field. We prove modularity lifting theorems for regular nn-dimensional Galois representations over FF without any self-duality condition. We deduce that all elliptic curves EE over FF are potentially modular, and furthermore satisfy the Sato--Tate conjecture. As an application of a different sort, we also prove the Ramanujan Conjecture for weight zero cuspidal automorphic representations for GL2(AF)\mathrm{GL}_2(\mathbf{A}_F).

Comments

A number of details have been included to address the concerns of the referees. The definition of decomposed generic (Def 4.3.1) has been weakened slightly to be in line with the current version of arxiv.org/abs/1909.01898, resulting in a strengthening of a number of our theorems. This is the accepted version of the paper
