Supersingular Hecke modules as Galois representations

Abstract

Let FF be a local field of mixed characteristic, let kk be a finite extension of its residue field, let H{\mathcal H} be the pro-pp-Iwahori Hecke kk-algebra attached to GLd+1(F){\rm GL}_{d+1}(F) for some d1d\ge1. We construct an exact and fully faithful functor from the category of supersingular H{\mathcal H}-modules to the category of Gal(F/F){\rm Gal}(\overline{F}/F)-representations over kk. More generally, for a certain kk-algebra H{\mathcal H}^{\sharp} surjecting onto H{\mathcal H} we define the notion of \sharp-supersingular modules and construct an exact and fully faithful functor from the category of \sharp-supersingular H{\mathcal H}^{\sharp}-modules to the category of Gal(F/F){\rm Gal}(\overline{F}/F)-representations over kk.
