本文的主要目的是将模曲线的著名的艾希勒 - 志村同余关系推广到志村群\(G\)在固定素数\(p\)上分裂的\(PEL\)型志村簇。特别地,我们证明了布拉休斯和罗加夫斯基对于这些志村簇的一个猜想。此外,我们根据\(G\)的根系数据给出了一个关于循环的公式,该循环是赫克算子\(T_p\)到正特征的约化,并在两个例子中计算了这个循环。《数学评论》分类:14K10,14L05,20G25
The main purpose of this paper is the generalization of the well-known Eichler-Shimura congruence relations for modular curves to Shimura varieties of PELtype whose Shimura group G is split over a fixed prime p. In particular we prove a conjecture of Blasius and Rogawski for these Shimura varieties. Further we give a formula for the cycle which is the reduction to positive characteristic of the Hecke operator Tp in terms of the root data of G and calculate this cycle in two examples.
