Stratifications in the reduction of Shimura varieties

Xuhua He, Michael Rapoport

摘要:

本文研究了一般Shimura簇的约化模$p$中的四个分层:Newton分层,Kottwitz-Rapoport分层,Ekedahl-Oort分层和Ekedahl-Kottwitz-Oort-Rapoport分层.我们制定了一个系统的公理,并表明,这些意味着非空的声明和封闭关系的声明,这些不同的分层。这些公理在西格尔的例子中得到了满足。

英文摘要:

In the paper four stratifications in the reduction modulo $p$ of a general Shimura variety are studied: the Newton stratification, the Kottwitz-Rapoport stratification, the Ekedahl-Oort stratification and the Ekedahl-Kottwitz-Oort-Rapoport stratification. We formulate a system of axioms and show that these imply non-emptiness statements and closure relation statements concerning these various stratifications. These axioms are satisfied in the Siegel case.
