Title: The Tilting conjecture (Part II)
Date: Wed, Nov 26, 2014, 13:15 - 14:45
Place: Seminar Room B
Abstract: Let G be a reductive group. The tilting conjecture of Feigin-Finkelberg-Kuznetsov-Mirkovic gives a geometric expression of semi-infinite cohomology of the small quantum group with coefficients in a tilting module for the big quantum group in terms of the Eisenstein series sheaf. In this talk we will show how to derive this conjecture via the technique of chiral categories. We will also give another derivation from the (still conjectural) global Geometric Langlands conjecture.
