摘要: We study the holographic description of string theory in a plane wave spacetime by taking Penrose limit usual AdS/CFT correspondence. consider three-point functions with two BMN operators and one non-BMN operator; latter should go over to perturbation dual CFT. On side we take metric produced operator, state propagates this perturbed background. The work Lee, Minwalla, Rangamani, Seiberg shows that for chiral AdS agree those calculated free gauge theory. However, when is reduced an effective amplitude truncating propagate from boundary geodesic, find puzzling mismatch. discuss possible resolutions, future directions.
