Star shaped quivers with flux

Abstract

We study the compactification of the 6d $\mathcal{N}=(2,0)$ SCFT on the product of a Riemann surface with flux and a circle. On the one hand, this can be understood by first reducing on the Riemann surface, giving rise to 4d $\mathcal{N}=1$ and $\mathcal{N}=2$ class $\mathcal{S}$ theories, which we then reduce on $S^1$ to get 3d $\mathcal{N}=2$ and $\mathcal{N}=4$ class $\mathcal{S}$ theories. On the other hand, we may first compactify on $S^1$ to get the 5d $\mathcal{N}=2$ Yang-Mills theory. By studying its reduction on a Riemann surface, we obtain a mirror dual description of 3d class $\mathcal{S}$ theories, generalizing the star-shaped quiver theories of Benini, Tachikawa, and Xie. We comment on some global properties of the gauge group in these reductions, and test the dualities by computing various supersymmetric partition functions.
