Non-Supersymmetric SO(3)-Invariant Deformations of N=1* Vacua and their Dual String Theory Description

We study the SO(3)-invariant relevant deformations of N=4 SU(N) gauge theory using the methods of Polchinski and Strassler. We present the region of parameter space where the non-supersymmetric vacuum is still described by stable ``dielectric’’ five branes within the supergravity approximation.
