AGT-correspondences give profound relations between certain families of N=2 supersymmetric gauge theories in four dimensions and conformal field theories in two dimensions. Subsequent investigations of the AGT-correspondences revealed a new type of topological field theory associated to these theories that captures completely the dependence of important physical quantities on the gauge coupling constants, including perturbative and non-perturbative corrections.

The topological field theories associated to N=2 gauge theories are the central objects of study in this project. We propose to develop a precise mathematical framework for them in which loop and surface operators will play a particularly important role. We also plan to generalize these structures to a wider class gauge theories and to investigate relations with topological string theory.
