摘要
对于超刚性 regime 中的Shimura簇和整齐水平子群,我们证明与数域点相关的标准-进表示族,,构成-表示的一个相容系统:存在整数使得对所有,在之外非分歧,且对所有和,与的共轭类的半单部分(是-有理且)相等。我们从内连通Shimura簇上标准-值局部系统的一个更强的相容性结果推导出这一点。我们的定理尤其适用于非阿贝尔型的Shimura簇,并代表了非阿贝尔型中首个此类与无关的结果。

At referee's advice, the preliminary section on tame specialization has been deleted, and the abstract results for superrigid local systems have been presented in less generality. A few small corrections (especially the end of Prop 2.3) and other minor expository changes have been made
