Abstract

Let G be a connected p-divisible group of height h and dimension d over a perfect field k, and O denote the ring of Witt vectors over k. It is a well-known fact that the deformation functor DefG is representable by Spf OO[[t₁,t_d(h-d)]]. Following Hazewinkel's philosophy we construct explicitly a family of universal deformations of G.
