Hodge stratification in low dimension
Stéphane Bijakowski
We define and study the Hodge stratification for the special fiber of Shimura varieties defined with the Pappas-Rapoport condition, in the case of low ramification index ($e \leq 3…

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…
