REPORT ON THE PIERRE DELIGNE FELLOWSHIP, 2011 SERGEY OBLEZIN During 2011 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated with Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...
