Abstract

We analyse the Seiberg Witten curve describing the N=2 gauge theory dual to the supergravity solution with fractional branes. Emphasis is given to those aspects that are related to stringy mechanism known as the enhancon. We also compare our results with the features of the supergravity duals, which have been variously interpreted in the literature. Known aspects of the N=2 gauge theories seem to agree with the supergravity solution, whenever the two theories can be faithfully compared.
