Supersingular Hecke modules as Galois representations

Abstract

Let $F$ be a local field of mixed characteristic $(0, p)$ , let $k$ be a finite extension of its residue field, let $ℋ$ be the pro- $p$ -Iwahori Hecke $k$ -algebra attached to ${GL}_{d + 1} (F)$ for some $d \geq 1$ . We construct an exact and fully faithful functor from the category of supersingular $ℋ$ -modules to the category of $Gal (\bar{F} ∕ F)$ -representations over $k$ . More generally, for a certain $k$ -algebra $ℋ^{♯}$ surjecting onto $ℋ$ we define the notion of $♯$ -supersingular modules and construct an exact and fully faithful functor from the category of $♯$ -supersingular $ℋ^{♯}$ -modules to the category of $Gal (\bar{F} ∕ F)$ -representations over $k$ .
