Igusa Stacks and the Cohomology of Shimura Varieties II
Patrick Daniels, Pol van Hoften, Dongryul Kim +1
We construct Igusa stacks for all Shimura varieties of abelian type and derive consequences for the cohomology of these Shimura varieties. As an application, we prove that the Farg…

Canonical Integral Models of Shimura Varieties of Abelian Type
Patrick Daniels, Alex Youcis
We prove a conjecture of Pappas and Rapoport for all Shimura varieties of abelian type with parahoric level structure when by showing that the Kisin-Pappas-Zhou integral mode…
