On the geometry of the Pappas-Rapoport models for PEL Shimura varieties
Stéphane Bijakowski, Valentin Hernandez
We study integral models, so-called Pappas-Rapoport or splitting models, of some PEL Shimura Varieties whose data are ramified at a prime p. We show that except in a specific case,…

The compatibility with the duality for partial Hasse invariants
Stéphane Bijakowski
We give a simple and natural proof for the compatibility of the Hasse invariant with duality. We then study a -divisible group with an action of the ring of integers of a finite…

Classicité de formes modulaires de Hilbert
Stéphane Bijakowski
We prove in this paper a classicality result for overconvergent Hilbert modular forms. To get this result, we use the analytic continuation method, first used by Buzzard and Kassae…
