摘 要:In this third talk of the series, we shall discuss the Koszul duality functors on the BGG category O and their parabolic analogues of any semisimple Lie algebras. In particular, we give the Z-graded decomposition numbers formulae for any integral blocks of the parabolic category O. Furthermore, we apply the Koszul duality to the study of the translated simple module M(x,y).
