Kazhdan-Lusztig conjecture via Zastava spaces

Representation Theory 2022-06-17 v2 Algebraic Geometry

Abstract

We deduce the Kazhdan-Lusztig conjecture on the multiplicities of simple modules over a simple complex Lie algebra in Verma modules in category O from the equivariant geometric Satake correspondence and the analysis of torus fixed points in zastava spaces. We make similar speculations for the affine Lie algebras and W-algebras.
