-==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.
