Applying to good reductions of Shimura varieties of Hodge type, we recover the Ekedahl-Oort stratifications by constructing universal de Rham $F$-gauges with $G$-structure. We also study the cohomology of de Rham $F$-gauges on these varieties. In particular, in the PEL type case and when the weights of the flat automorphic vector bundles are $p$-small, we determine the $F$-gauge structure on their de Rham cohomology by the associated dual BGG complexes.", "revisions": [ { "version": "v2", "updated": "2024-07-17T10:37:04.000Z" } ], "analyses": { "subjects": [ "11G18", "14G35" ], "keywords": [ "shimura varieties", "rham cohomology", "flat automorphic vector bundles", "pel type case", "smooth algebraic varieties" ], "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable" } } }
