A class of p-adic Galois representations arising from abelian varierties over Qp

Abstract

Let V be a p-adic representation of the absolute Galois group G of Qp that becomes crystalline over a finite tame extension, and assume p odd. We provide necessary and sufficient conditions for V to be isomorphic to the Tate module Vp(A) of an abelian variety A defined over Qp. These conditions are stated on the filtered (φ,G)-module attached to V.
