A-D hypersurface of su(n) 𝒩=2 supersymmetric gauge theory with Nf=2n−2 flavors

Abstract

In the previous paper, arXiv:2210.16738[hep-th], we found a set of flavor mass relations as constraints such that the [Formula: see text]-deformed [Formula: see text] quiver matrix model restores the maximal symmetry in the massive scaling limit and reported the existence of Argyres–Douglas critical hypersurface. In this paper, we derive the concrete conditions on moduli parameters which maximally degenerates the Seiberg–Witten curve while maintaining the flavor mass relations. These conditions define the A-D hypersurface.
