LARGE-N REDUCTION FOR $\mathcal{N} = 2$ CHERN-SIMONS THEORIES AND LOCALIZATION

We study reduced matrix models obtained by the dimensional reduction of quiver Chern-Simons theories on S3 and show that, around a certain multiple fuzzy sphere background, the reduced models are equivalent to the original theories in the large-N limit. This is regarded as a large-N reduction on S3. By using the localization technique, we prove the large-N equivalence with respect to supersymmetric observables.
