Modularity of ${\mathrm{PGL}}_2({\mathbb{F}}_p)$-representations over totally real fields

Abstract

We study an analogue of Serre's modularity conjecture for projective representations $\overline{\rho }:\mathrm{Gal}(\overline{K}/K)\to {\mathrm{PGL}}_2(k)$, where $K$ is a totally real number field. We prove new cases of this conjecture when $k={\mathbb{F}}_5$ by using the automorphy lifting theorems over CM fields established in previous work of the authors.
