课程描述

In this course I will present some advanced topics related with gauged linear sigma models (GLSM). I will mainly focus on how to get derived equivalences and functors between triangulated categories related to CY geometries, mathematically, this  is a generalization of Orlov’s equivalence and in physics  terms this is about correspondences of B-brane categories as we move on the quantum Kahler moduli space.  I will also present extensions of these results to non-CY cases. As time allows I will also present other modern topics such as Seiberg-like dualities and the incorporation of B-type domain walls on GLSMs and their categorical interpretation.
