N = 1 supersymmetric renormalization group flows from IIB supergravity

We consider J = 1 supersymmetric renormalization group flows of Af = 4 Yang-Mills theory from the perspective of tendimensional IIB supergravity. We explicitly construct the complete ten-dimensional lift of the flow in which exactly one chiral superfield becomes massive (the LS flow). We also examine the ten-dimensional metric and dilaton configurations for the "super-QCD" flow (the GPPZ flow) in which all chiral superfields become massive. We show that the latter flow generically gives rise to a dielectric 7-brane in the infra-red, but the solution
