摘要

We prove a conjecture of Pappas and Rapoport about the existence of “canonical” integral models of Shimura varieties of Hodge type with quasi-parahoric level structure at a prime p. For these integral models, we moreover show uniformization of isogeny classes by integral local Shimura varieties and prove a conjecture of Kisin and Pappas on local model diagrams.
