The model of Dvali, Gabadadze, and Porrati (DGP) gives a simple geometrical setup in which gravity becomes 5-dimensional at distances larger than a length scale lambda(DGP). We show that this theory… Expand

We suggest a mechanism by which four-dimensional Newtonian gravity emerges on a 3-brane in 5D Minkowski space with an infinite size extra dimension. The worldvolume theory gives rise to the correct… Expand

We nd new, local, non-supersymmetric conformal eld theories ob- tained by relevant deformations of the N=4 super Yang Mills theory in the large N limit. We contruct interpolating supergravity… Expand

We examine various aspects of the conjectured duality between warped AdS5 geometries with boundary branes and strongly coupled (broken) conformal field theories coupled to dynamical gravity. We also… Expand
