Abstract

In this note we explore the stringy interpretation of non-perturbative ef- fects in N = 1∗ deformations of the Ak−1 quiver models. For certain types of deforma- tions we argue that the massive vacua are described by Nk fractional D3-branes at the orbifold polarizing into k concentric 5-brane spheres...
