Categorified -Schur algebra and the BMW algebraIn 1989 François Jaeger showed that the the Kauffman polynomial of a link can be obtained as a weighted sum of HOMFLYPT polynomials on certain links associated to . In this talk I will explain how to use a version of Jaeger's theorem to stablish a connection between the and the -Schur algebras. I will then present a subcategory of the Schur category which categorifies the algebra (joint with E. Wagner).
