题目：Ekedahl-Oort stratification of Shimura varieties via Breuil-Kisin windows

报告人：闫旗军博士 (Leiden University and University of Milan)

Abstract: I will recall the classification of p-divisible groups in terms of filtered Breuil-Kisin modules (or Breuil-Kisin windows, in our term), and then explain why the Frobenii of Breuil-Kisin windows can be used to define the Ekedahl-Oort stratification of Shimura varieties and how to give a direct map from the Shimura variety in question to some subquotient sheaf of its associated loop group whose geometric points parametrize Viehmann's new invariants "truncations of level 1 of elements of loop groups".
