DESCRIPTION:I will relate the endomorphism algebra of a minimal projective
  generator for a block of the general linear supergroup to a limiting vers
 ion of Khovanov's diagram algebra. One consequence is that blocks of the g
 eneral 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.\n
