pp waves and holography
Abstract
We consider aspects of holography in the ppwave limit of AdS_{5}×S^{5}. This geometry contains two R^{4}'s, one obtained from AdS_{5} directions, and the other from the S^{5}. We argue that the holographic direction in the ppwave background can be taken to be r, the radial direction in the first R^{4}. Normalizable modes correspond to states, and nonnormalizable modes correspond to deformations of the boundary theory. In the strict ppwave limit, there are additional nonnormalizable modes in the second R^{4}, which have no apparent superYangMills interpretation. We outline the procedure for calculating correlation functions holographically.
