SUMMARY:Boundaries and duality for 3d gauge theories
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeaker: Ben Gammage\, Harvard University \nTitle: Boundaries and duality for 3d gauge theories \nAbstract: 3d N=4 supersymmetric gauge theory has a pair of topological twists\, the A-model and B-model\, the latter of which is also known as Rozansky-Witten theory. Conjecturally\, boundary conditions for these TFTs ought to admit descriptions in terms of (microlocal) perverse or coherent sheaves of categories\, respectively. Unfortunately\, neither of these admits a general mathematical definition; nevertheless\, in some cases these are well-defined 2-categories. We will survey these situations and the duality\, known as 3d mirror symmetry\, which relates the A- and B-models of different theories\, together with its relation to the relative Langlands duality of Ben-Zvi–Sakellaridis-Venkatesh.
