Twisting with a Flip

I will consider N=2 supersymmetric Yang-Mills theory on 4D 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.
