Maths HEP Lunchtime Seminars: Supersymmetric partition functions and the A-twist
3 February 2017 13:00 in CM221
I will present new results about 3d N=2 supersymmetric partition functions (and certain Wilson loops) on three-manifolds that are circle bundles over Riemann surfaces. This includes the well-known S^3 partition function. I will explain how all the information contained in these curved-space objects is more simply encoded in a two-dimensional topological A-model that governs the Coulomb branch of the theory compactified on a circle.
