References

For this lecture, useful references include: Chuang and Rouquier, Derived equivalences for symmetric groups and sl2-categorification (first applies principle of reducing to minimal categorifications, and constructs derived equivalences lifting Weyl group elements) Rouquier, 2-Kac-Moody algebras (really runs with this principle, and applies it in some new ways) Lauda, A categorification of quantum sl(2) and Categorified quantum sl(2) and equivariant cohomology of iterated flag varieties (goes much more heavily to into 2-category philosophy and diagrammatics) The slides for the talk are on my webpage at
