$\mathcal{N}=2$ gauge theories on unoriented/open four-manifolds and their AGT counterparts

Aditya Bawane, Sergio Benvenuti, Giulio Bonelli +2

We compute the exact path integral of $\mathcal{N}=2$ supersymmetric gauge theories with general gauge group on ${\mathbb{RP}}^4$ and a ${\mathbb{Z}}_2$-quotient of the hemi-$S^4$. By…
