Let be a finite field of characteristic , let be a smooth affine group scheme over , and let be a cocharacter of such that the set of $μ…
(G, μ)-displays and Rapoport-Zink spaces
O. Bueltel, G. Pappas
Let (G, μ) be a pair of a reductive group G over the p-adic integers and a minuscule cocharacter μ of G defined over an unramified extension. We introduce and study "(G, μ)-display…
The congruence relation in the non-PEL case
Oliver Bueltel
This work settles the Eichler-Shimura congruence relation of Blasius and Rogawski for certain 5-dimensional Hodge-type Shimura varieties, that were not tractable by previously know…
Embeddings of the complex ball into Siegel space
Oliver Bueltel
We study properties of a map from a certain unitary group in variables to a related unitary group in variables. We explain how it gives rise to a map between can…
On the supersingular loci of quaternionic Siegel space
Oliver Bueltel
The paper studies the supersingular locus of the characteristic p moduli space of principally polarized abelian 8-folds that are equipped with an action of a maximal order in a qua…
Congruence relations for Shimura varieties associated to some unitary groups
O. Bueltel, T. Wedhorn
In this paper we study the reduction of PEL-Shimura varieties associated to unitary groups of signature (n-1,1) in the inert and unramified case. We describe the Newton polygon and…
