Randall-Sundrum models and the regularized AdS/CFT correspondence

It has been proposed that Randall-Sundrum models can be holographically des cribed by a regularized (broken) conformal field theory. We analyze the fou ndations of this duality using a regularized version of the AdS/CFT corresp ondence. We compare two- and three-point correlation functions and find the same behaviour in both descriptions. In particular, we show that the regul arization of the deformed CFT generates kinetic terms for the sources, whic h hence can be naturally treated as dynamical fields. We also discuss the c ounterterms required for two- and three-point correlators in the renormaliz ed AdS/CFT correspondence.
