Kevin Purbhoo "Jeu de taquin and Schubert intersections"

Syu Kato "Deformations of nilpotent cones and Springer correspondences"

Abstract:
Let G = Sp (2n) be the symplectic group over Z. We present a certain kind of deformation of the nilpotent cone of G with G-action. This enables us to compare the Springer correspondence of sp_{2n} over C, that over characteristic two, and our exotic Springer correspondence.
