Mixed modular perverse sheaves on affine flag varieties and Koszul duality
Simon Riche
Under some technical assumptions, and building on joint work with Bezrukavnikov, we prove a multiplicity formula for indecomposable tilting perverse sheaves on affine flag varietie…
A modular ramified geometric Satake equivalence
Pramod N. Achar, João Lourenço, Timo Richarz +1
We extend the ramified geometric Satake equivalence due to Zhu (for tamely ramified groups) and the third named author (in full generality) from rational coefficients to include mo…
Some applications of the geometric Satake equivalence to modular representation theory
Simon Riche
These notes present an application of the geometric Satake equivalence to the description of characters of indecomposable tilting modules for reductive algebraic groups over fields…
On two modular geometric realizations of an affine Hecke algebra
Roman Bezrukavnikov, Simon Riche
In this paper we construct equivalences of monoidal categories relating three geometric or representation-theoretic categorical incarnations of the affine Hecke algebra of a connec…
