Koszul duality for Kac-Moody groups and characters of tilting modules
Pramod Achar, Shotaro Makisumi, Simon Riche +1
We establish a character formula for indecomposable tilting modules for connected reductive groups in characteristic p in terms of p-Kazhdan-Lusztig polynomials, for p>h the Coxete…
Mixed modular perverse sheaves on moment graphs
Shotaro Makisumi
We study an analogue of the Achar-Riche "mixed modular derived category" for moment graphs. In particular, given a Coxeter group and a reflection faithful representation $\math…
Free-monodromic mixed tilting sheaves on flag varieties
Pramod N. Achar, Shotaro Makisumi, Simon Riche +1
In this paper we propose a construction of a monoidal category of "free-monodromic" tilting perverse sheaves on (Kac-Moody) flag varieties in the setting of the "mixed modular deri…
Modular Koszul duality for Soergel bimodules
Shotaro Makisumi
We generalize the modular Koszul duality of Achar-Riche to the setting of Soergel bimodules associated to any finite Coxeter system. The key new tools are a functorial monodromy ac…
