报告内容简介：A finite-dimensional Lie superalgebra g=g_0+g_1 is called classical if the restriction of the adjoint representation of g to the Lie algebra g_0 is completely reducible. It follows from Kac's classification that every finite-dimensional simple complex Lie superalgebra is classical except for those belonging to the so-called Cartan series. Tilting modules in the BGG category O for most of the simple classical Lie superalgebras have been studied by Brundan following Soergel's approach. In this talk, we will introduce a version of Ringel duality for the parabolic versions of the category O of a general classical Lie superalgebra. This talk is based on joint work with Shun-Jen Cheng and Kevin Coulembier.
