Cascading Quivers from Decaying D-branes

Abstract

We use an argument analogous to that of Kachru, Pearson and Verlinde to argue that cascades in La,b,c quiver gauge theories always preserve the form of the quiver, and that all gauge groups drop at each step by the number M of fractional branes. In particular, we demonstrate that an NS5-brane that sweeps out the S3 of the base of La,b,c destroys M D3-branes.
