SUMMARY:David Nadler: \"Springer theory for symplectic geometers\"
DESCRIPTION:Abstract: In its modern formulation\, Springer's theory of W
 eyl group representations involves perverse sheaves on the nilpotent con
 e of a Lie algebra. I will explain a much more down-to-earth viewpoint o
 n this subject via symplectic geometry and Floer theory. I will also dis
 cuss how it appears as a toy model of the Geometric Langlands program.
