Maths HEP Lunchtime Seminars: A geometric recipe for twisted superpotentials

Presented by Lotte Hollands, Heriot-Watt University

8 December 2017 13:00 in CM221

Nekrasov, Rosly and Shatashvili observed that the generating function of a certain space of SL(2) opers has a physical interpretation as the effective twisted superpotential for a four-dimensional N=2 quantum field theory. In this talk we describe the ingredients needed to generalise this observation to higher rank. Important ingredients are spectral networks generated by Strebel differentials and the abelianization method. As an example we find the twisted superpotential for the E6 Minahan-Nemeschansky theory.
