Abstract:
I will talk on a "classification" of isogeny classes of p-divisible groups with saturated Newton polygons.This topic can be regarded as an extension of Dieudonne-Manin classification over algebraically closed fields (and over perfect fields), the generalization by Zink over regular rings (including the case of imperfect fields) and that by Oort-Zink over normal noetherian rings.When we consider a family of p-divisible groups, the assumption that Newton polygon is constant was always necessary. But we shall weaken it to the assumption that the family has saturated Newton polygons.
