Algebra Seminar: Hausel -- Ringifying intersection cohomology

Tamas Hausel (Institute of Science and Technology Austria) will be speaking in the
algebra seminar.  We will go out for lunch after the talk---all are welcome to join! 

When: 12-1pm Friday October 24 

Where: Carslaw 175 

Title: Ringifying intersection cohomology 

Abstract: Although there is no natural ring structure on intersection cohomology, in the
case of affine and finite Schubert varieties also at their singular points, partly
conjecturally, we ringify intersection cohomology using our big algebra approach to
geometric representation theory of compact and complex Lie groups.
