报告摘要：This talk is based on a joint work with Jun Hu, which comes from our second attempt for studying the invariant theory of quantized orthogonal groups. We use the dominant dimension to study the double centralizer property and provide a criterion for a tilting module of a standardly stratified algebra satisfying the double centralizer property. Moreover, if A is a quasi-hereditary algebra with a simple preserving duality and T is a faithful tilting A-module, then A has the double centralizer property with respect to T. We also affirmatively answer an open question of Mazorchuk and Stroppel.
