From families in Weyl groups to unipotent elements

Abstract: In geometric representation theory one tries to understand group representations using geometry. But sometimes one can try to go in the opposite direction. In this talk we will illustrate this by showing that a number of features in geometry (such as Springer correspondence attached to unipotent classes) can be recovered from pure algebra (such as the generic degrees of representations of Weyl groups).
