Title: Kazhdan-Lusztig conjecture via zastava spaces
Abstract: This is a joint work with A.Braverman and H.Nakajima. We give yet another proof (a geometric one) of the famous Kazhdan-Lusztig conjecture on the characters of irreducible modules in the category O over a complex semisimple Lie algebra (in the Koszul-dual formulation). The proof proceeds by analysis of fixed points in the zastava spaces..
