摘 要：In this fourth talk of the series, we shall discuss the twisting functors and their Z-graded lifts on the BGG category O of any semisimple Lie algebras. We consider their actions on Verma modules, dual Verma modules and simple modules. We also discuss their right adjoints and derived versions which induce an auto-equivalence of derived categories.
