N=1 super Yang-Mills theories and wrapped branes

I consider supergravity solutions of D5 branes wrapped on supersymmetric 2-cycles and use them to discuss relevant features of four-dimensional 1 super Yang-Mills theories with gauge group SU(N). In particular, using a gravitational dual of the gaugino condensate, it is shown that it is possible to obtain the complete NSVZ -function. It is also described how different aspects of the gauge theory are nicely encoded in this supergravity solution.
