分歧情况下的局部模型。II。拆分模型

Local models in the ramified case. II. Splitting models

G. Pappas, M. Rapoport

摘要:

本文是我们的数学论文AG/0006222的继续。我们研究了某些PEL Shimura品种parahoric水平结构在素数p的减少,在该组定义的Shimura品种分歧。我们描述了这些Shimura簇的“好”的$p$ -adic积分模型,并研究了它们的etale局部结构.特别是,我们展示了他们的(奇异)特殊纤维的分层,并给出了附近的周期层的部分计算。

英文摘要:

This paper is a continuation of our paper math.AG/0006222. We study the reduction of certain PEL Shimura varieties with parahoric level structure at primes p at which the group that defines the Shimura variety ramifies. We describe "good" $p$-adic integral models of these Shimura varieties and study their 'etale local structure. In particular, we exhibit a stratification of their (singular) special fibers and give a partial calculation of the sheaf of nearby cycles.
