Abstract
In light of the anti–de Sitter space conformal field theory correspondence, it is natural to try to define a conformal field theory in a large N, strong coupling limit via a supergravity compactification on the product of an Einstein manifold and anti–de Sitter space. We consider the five-dimensional manifolds which are coset spaces The central charge and a part of the chiral spectrum are calculated, respectively, from the volume of and the spectrum of the scalar Laplacian. Of the manifolds considered, only admits any supersymmetry: it is this manifold which characterizes the supergravity solution corresponding to a large number of -branes at a conifold singularity, discussed recently by Klebanov and Witten. Through a field theory analysis of anomalous three point functions we are able to reproduce the central charge predicted for the theory by supergravity: it is of the central charge of the orbifold theory from which it descends via a renormalization group flow.
