Abstract

We construct a class of intersecting brane solutions with horizon geometries of the form adS_k x S^l x S^m x Eⁿ. We describe how all these solutions are connected through the addition of a wave and/or monopoles. All solutions exhibit supersymmetry enhancement near the horizon. Furthermore we argue that string theory on these spaces is dual to specific superconformal field theories in two dimensions whose symmetry algebra in all cases contains the large N=4 algebra A_gamma. Implications for gauged supergravities are also discussed.
