Kazhdan-Lusztig conjecture via Zastava spaces
arXiv:2007.09799 · doi:10.1515/crelle-2022-0013
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.
