Abstract
We construct a moduli space of Kisin modules with tame descent datum and with fixed -adic Hodge type , for some finite extension . We show that this space is smoothly equivalent to the local model for , cocharacter , and parahoric level structure. We use this to construct the analogue of Kottwitz-Rapoport strata on the special fiber indexed by the -admissible set. We also relate to potentially crystalline Galois deformation rings.
