DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UMassRep/14/
 ">Category O via Zastava spaces</a>\nby Alexander Braverman (University of
  Toronto) as part of UMass Amherst Representation theory seminar\n\n\nAbst
 ract\nIn my talk I will recall basic results about category O for\nfinite-
 dimensional and affine Lie algebras - such as Kazhdan-Lusztig\nconjecture\
 , Jantzen conjecture etc. I will then describe a new\ngeometric approach t
 o proving these conjectures via so called Zastava\nspaces. developed in my
  recent paper with Finkelberg and Nakajima. In\nthat paper we give a new p
 roof of the Kazhdan-Lusztig conjecture for\nsemi-simple Lie algebras\, I w
 ill describe how it should be possible to\nextend this to Jantzen conjectu
 res and to the affine case.\n
