摘要： 在引力/规范对偶的框架下，推导了全息电流及其相关的Ward恒等式。展示了与Ward恒等式一致的能量动量张量和R-对称性电流的全息改进。将特定弦环修正对整体作用量的影响包括在内，并确定其对边界理论的迹 anomaly 和R-对称性 anomaly 的贡献。作为一个例子，该构造被应用于N=2共形超重力，它被认为是与边界SU(N)xSU(N)，N=1超共形场论对偶。 显示英文摘要

摘要： Holographic currents and their associated Ward identities are derived in the framework of gravity/gauge duality. Holographic improvements of the energy-momentum tensor and R-symmetry current which are consistent with the Ward identities are displayed. The effects of specific string loop corrections to the bulk action are included as four derivative effective lagrangian terms and their contributions to the trace and R-symmetry anomalies of the boundary theory are determined. As an example, the construction is applied to the N=2 conformal supergravity which is taken to be dual to a boundary SU(N)xSU(N), N=1 superconformal field theory.
