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.



Some knowledge of 2d (2,2) supersymmetric QFTs  is required as well as some basic algebraic geometry. No previous knowledge on categories will be assumed.
