摘要
设 为一个 Shimura datum。我们于前期与 Christian Klevdal 合作已证明,对于 的规范 -值局部系统在投影到 的伴随群后形成兼容系统。本文我们强化该结果,证明 -局部系统本身也具有兼容性。我们还包括晶体兼容性,扩展了我们合作工作中 Jake Huryn、Kiran Kedlaya 和 Christian Klevdal 所建立的伴随情形。

备注
Comments welcome. This update: (1) fixes some cross-referencing with our joint work with Huryn, Kedlaya, and Klevdal; (2) gives more details on companions with reductive monodromy group; (3) changes the title to avoid confusion with our previous work with Klevdal
