A categorification of the Lusztig--Vogan module

Representation Theory 2022-07-15 v2 Algebraic Geometry

Abstract

We construct two categorifications of the Lusztig--Vogan module associated to a real reductive algebraic group. The first categorification is given by semisimple complexes in an equivariant derived category, and the second is constructed as a module category over Soergel bimodules. Our categorifications are related by taking equivariant hypercohomology.
