几个Shimura簇的坏约化的环面分解

A toroidal resolution for the bad reduction of some Shimura varieties

A. Genestier

摘要:

借用一个减少原则,以最近的预印本G。Faltings(toroidal resolution of some matrix singularities,1999),我们利用PGL_r^{N+1}/PGL_r的Lafforgue紧化,构造了p处具有仿射水平结构的酉辛型Shimura簇的素数p中坏约化的正则对数光滑toroidal resolution,利用这个结果,可以导出Z_p[p^{1/v}]上的非正则半稳定resolution.

英文摘要:

Borrowing a reduction principle to a recent preprint of G. Faltings (toroidal resolution of some matrix singularities, 1999), we use Lafforgue's compactification of PGL_r^{N+1}/PGL_r to construct a canonical log-smooth toroidal resolution for the bad reduction in a prime p of Shimura varieties of unitary and symplectic type with parahoric level structures at p. Using this result, non-canonical semi-stable resolutions over Z_p[p^{1/ν}] can be derived.
