摘要
We explain a geometric construction on the Pappas-Rapoport Splitting models of Shimura varieties. More precisely, we construct F-zips with additional structure of fixed type on good reductions of splitting models and their toroidal compactifications. Combined with the method of Goldring-Koskivirta on group theoretical Hasse invariants, this leads to a construction of Galois pseudo-representations associated to torsion classes in coherent cohomology in the ramified setting. This is a joint work with Y. Zheng.
