報(bào)告簡介:
We explain certain categories of Whittaker modules over the general linear Lie superalgebras that can be realized as properly stratified categories. These categories turn out to be equivalent to certain Serre quotients of the BGG category O. Using this realization we show that these Whittaker categories categorify certain q-symmetric Fock spaces over the infinite-rank quantum group of type A. In this picture, the canonical and dual canonical bases in these q-symmetric Fock spaces correspond to tilting and simple objects in these Whittaker categories, respectively. This talk is based on a joint work with Chih-Whi Chen and Volodymyr Mazorchuk.
