On the rigid cohomology of certain Shimura varieties

M Harris, KW Lan, R Taylor, J Thorne - Research in the Mathematical …, 2016 - Springer
We construct the compatible system of l-adic representations associated to a regular
algebraic cuspidal automorphic representation of GL_n GL n over a CM (or totally real) field …

Modularity lifting beyond the Taylor–Wiles method

F Calegari, D Geraghty - Inventiones mathematicae, 2018 - Springer
We prove new modularity lifting theorems for p-adic Galois representations in situations
where the methods of Wiles and Taylor–Wiles do not apply. Previous generalizations of …

Strata Hasse invariants, Hecke algebras and Galois representations

W Goldring, JS Koskivirta - Inventiones mathematicae, 2019 - Springer
We construct group-theoretical generalizations of the Hasse invariant on strata closures of
the stacks G-Zip\nolimits^ μ G-Zip μ. Restricting to zip data of Hodge type, we obtain a group …

Comparison between analytic and algebraic constructions of toroidal compactifications of PEL-type Shimura varieties

KW Lan - Journal für die reine und angewandte Mathematik …, 2012 - degruyter.com
Using explicit identifications between algebraic and analytic theta functions, we compare the
algebraic constructions of toroidal compactifications by Faltings–Chai and the author, with …

p-adic cohomology and classicality of overconvergent Hilbert modular forms

Y Tian, L Xiao - arXiv preprint arXiv:1308.0779, 2013 - arxiv.org
Let $ F $ be a totally real field in which $ p $ is unramified. We prove that, if a cuspidal
overconvergent Hilbert cuspidal form has small slopes under $ U_p $-operators, then it is …

Nearby cycles of automorphic étale sheaves

KW Lan, B Stroh - Compositio Mathematica, 2018 - cambridge.org
We show that the automorphic étale cohomology of a (possibly noncompact) PEL-type or
Hodge-type Shimura variety in characteristic zero is canonically isomorphic to the …

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 …

[HTML][HTML] Vanishing theorems for torsion automorphic sheaves on general PEL-type Shimura varieties

KW Lan, J Suh - Advances in Mathematics, 2013 - Elsevier
We consider the interior cohomology (and the Hodge graded pieces in the case of the de
Rham realization) of general–not necessarily compact–PEL-type Shimura varieties with …

[PDF][PDF] An example-based introduction to Shimura varieties

KW Lan - Preprint, 2017 - javier.fresan.perso.math.cnrs.fr
In this introductory article, we will explain what Shimura varieties are and why they are
useful, with an emphasis on examples. We will also describe various compactifications of …

Nearly overconvergent Siegel modular forms

Z Liu - Annales de l'Institut Fourier, 2019 - numdam.org
Shimura developed his theory of nearly holomorphic forms in his study on the algebraicity of
special L-values and Klingen Eisenstein series [42, 45]. With the goal of combining this …
