Let k be an algebraically closed field of characteristic p > 0. Let D be a p-divisible group over k. Let nD be the smallest non-negative integer for which the following statement holds: if C is a p-divisible group over k of the same codimension and dimension as D and such that C ŒpD is isomorphic to DŒpD , then C is isomorphic to D. To the Dieudonné module… CONTINUE READING
