Lattices in Tate modules
Refining a theorem of Zarhin, we prove that, given ag-dimensional abelian variety X and an endomorphism u of X,there exists a matrixA∈M2g(Z) such that each Tate module T X has a Z -basis on which the action of u is given by A, and similarly for the covariant Dieudonné module if over a perfect field...
