introduction
- In his paper [Spr76], Springer defined a certain representation of the Weyl group of a reductive group on the cohomology of a set of fixed points in the flag variety by a nilpotent element, which we now call the Springer representation.
- In particular, for various sets of such fixed points, called Springer fibers, the top degree cohomology gives all the irreducible representations of the corresponding Weyl group.
- The Springer correspondence makes a link between the characters of a Weyl group and the geometry of the nilpotent cone of the corresponding semisimple Lie algebra
- extend this to an equivalence between the triangulated category generated by the Springer perverse sheaves and the derived category of differential graded modules over a dg-ring related to the Weyl group
nilpotent variety
- Given a semisimple algebraic group \(G\) with Lie algebra \(\mathfrak{g}\), we call the closure of a \(G\)-orbit in the nilpotent elements of \(\mathfrak{g}\) a nilpotent variety.
