Coherent sheaves on the stack of Langlands parameters

X Zhu - arXiv preprint arXiv:2008.02998, 2020 - arxiv.org
We formulate a few conjectures on some hypothetical coherent sheaves on the stacks of
arithmetic local Langlands parameters, including their roles played in the local-global …

l-Adic étale cohomology of Shimura varieties of Hodge type with non-trivial coefficients

P Hamacher, W Kim - Mathematische Annalen, 2019 - Springer
Abstract Let (G, X)(G, X) be a Shimura datum of Hodge type. Let p be an odd prime such that
G _ Q _p GQ p splits after a tamely ramified extension and p\not ∣| π _1 (G^ der)| p∤| π 1 (G …

On the generic part of the cohomology of local and global Shimura varieties

T Koshikawa - arXiv preprint arXiv:2106.10602, 2021 - arxiv.org
Using the work of Fargues-Scholze, we prove a vanishing theorem for the generic
unramified part of the cohomology of local Shimura varieties of general linear groups. This …

On the étale cohomology of Hilbert modular varieties with torsion coefficients

A Caraiani, M Tamiozzo - Compositio Mathematica, 2023 - cambridge.org
We study the étale cohomology of Hilbert modular varieties, building on the methods
introduced by Caraiani and Scholze for unitary Shimura varieties. We obtain the analogous …

Compactifications of subschemes of integral models of Shimura varieties

KW Lan, B Stroh - Forum of Mathematics, Sigma, 2018 - cambridge.org
We study several kinds of subschemes of mixed characteristic models of Shimura varieties
which admit good (partial) toroidal and minimal compactifications, with familiar boundary …

Igusa stacks and the cohomology of Shimura varieties
