Modular supercuspidal lifts of weight $2$
Abstract
Let be any totally real number field and an ideal of its ring of integers of norm and define, for every even , the -dimensional multiweight . We prove that for a non CM Hilbert cuspidal Hecke eigenform for , say with even, and a prime totally split in such that and such that the residual mod representation satisfies that , there exists a lift associated to a Hilbert modular cuspform for , say for some Nebentypus character which is supercuspidal at each prime of over . We also observe that our techniques provide an alternative proof to the corresponding statement for classical Hecke cuspforms already proved by Khare \cite{khare} with classical techniques. Finally, we take the opportunity to include a corrigenda for \cite{dieulefait} which follows from our main result, which provides a congruence that puts the micro good dihedral prime in the level.

This is a generalisation of main result in our the former version to Hilbert modular forms of parallel weight to (with p totally split in F)
