A generalization of the Springer resolution
Abstract:
The Springer resolution of the nilpotent cone of a semisimple Lie algebra has important
applications in representation theory, and in particular was used by Springer to give a geometric construction of the irreducible representations of Weyl groups. This talk concerns a generalization of the Springer resolution constructed with the use of toric varieties. We will discuss how this is connected in type A with Lusztig's generalized Springer correspondence, as well as an analogue of an affine paving of the fibers. Part of this talk is joint work with Martha Precup and Amber Russell.
