Abstract

We study an analog of Serre's modularity conjecture for projective representations [Formula: see text], where K is a totally real number field. We prove cases of this conjecture when [Formula: see text].

Highlights

  • Let K be a number field, and consider a continuous representation ρ : GK → GL2(k ), where k is a finite field

  • Serre’s conjecture and its generalizations assert that any ρ of S type should be automorphic

  • We say that σ is of S type if it is absolutely irreducible and totally odd, in the sense that if k has odd characteristic, for each real place v of K, σ(cv ) is nontrivial

Summary

Introduction

Let K be a number field, and consider a continuous representation ρ : GK → GL2(k ), where k is a finite field. In this paper we prove new cases of extensions of Serre’s conjecture to mod p representations of absolute Galois groups of totally real number fields.
