Blocks of the general linear supergroup
Seminar Room 1, Newton Institute
I will relate the endomorphism algebra of a minimal projective generator for a block of the general linear supergroup to a limiting version of Khovanov's diagram algebra. One consequence is that blocks of the general linear supergroup are Koszul, in the same spirit as classical work of Beilinson, Ginzburg and Soergel on blocks of the BGG category O for a semisimple Lie algebra. This is joint work with Catharina Stroppel.
