Abstract
We develop a new method to solve the irreducible character problem for a wide class of modules over the general linear superalgebra including all the finitedimensional modules by directly relating the problem to the classical KazhdanLusztig theory Furthermore we prove that certain parabolic BGG categories over the general linear algebra and over the general linear superalgebra are equivalent We also verify a parabolic version of a conjecture of Brundan on the irreducible characters in the BGG category of the general linear superalgebra
