DESCRIPTION:Title: <a href="https://researchseminars.org/talk/RAMpAGe/10/"
 >Mod p Hecke algebras and perverse F_p-sheaves</a>\nby Robert Cass (Harvar
 d University) as part of Recent Advances in Modern p-Adic Geometry (RAMpAG
 e)\n\n\nAbstract\nWe explain a mod $p$ version of the geometric Satake iso
 morphism which gives a sheaf-theoretic description of the spherical mod $p
 $ Hecke algebra. We also construct central elements in the Iwahori mod p H
 ecke algebra by adapting a method due to Gaitsgory. Our proofs rely crucia
 lly on the theory of $F$-singularities\, and along the way we prove new re
 sults about the singularities of affine Schubert varieties. We expect thes
 e results to have applications toward a mod $p$ Langlands correspondence.\
