摘要
We study the N = 2 supersymmetric analog of the Klebanov-Strassler system. We first review the resolution of singularities by the enhancon mechanism, and the physics of fractional branes on an orbifold. We then describe the exact N = 2 solution. This exhibits a duality cascade as in the N = 1 case, but the singularity resolution is the characteristic N = 2 enhancon. We discuss some related solutions and open issues.
