Perverse sheaves on the semi-infinite flag variety and representations of the Frobenius kernel (2504.03341v1)
Published 4 Apr 2025 in math.RT
Abstract: We study a category of Iwahori-equivariant modular perverse sheaves on some avatar of the semi-infinite flag variety, by adapting the work of Arkhipov-Bezrukavnikov-Braverman-Gaitsgory-Mirkovi\'c. We then construct a functor between the latter category and the category of graded representations of the Frobenius kernel, and conjecture that this functor is an equivalence.
