Non-conformal examples of AdS-CFT

Asymptotically anti-de Sitter spacetimes with Poincareinvariance along the boundary can describe, via the AdS-CFT correspondence, either relevant deformations of a conformal field theory or non-conformal vacuum states. I consider examples of both types constructed within the framework of five-dimensional gauged supergravity. I explain the proof and motivation of a gravitational `c -theorem' which is independent of dimension. I show how one class of examples can be elevated to ten-dimensional geometries involving distributions of parallel D3-branes. For these cases some peculiar properties of two-point functions emerge, and I close with speculations on their physical origin.
