... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon.

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to 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 . ...
