HET Brown Bag Seminar | Twisting with a flip
Guido Festuccia (Uppsala)
I will consider N=2 supersymmetric gauge theories on 4D compact manifolds with a Killing vector field with isolated fixed points. Studying the realization of supersymmetry in these theories leads to consider a generalization of the notion of self-duality on manifolds with a vector field. This allows to construct a framework unifying equivariant Donaldson-Witten theory and Pestun's theory on S4 and its generalizations. I will also discuss the action of S-duality in these theories.
