讨论了AdS/CFT对应中扰动引起的对称性破缺。考虑了向量场对六维N=（4，4）超引力AdS 3 × S3解的扰动.这些扰动被认为是具有共形权（2，2）或（1，1）的二维N=（4，4）CFT的手征原算子的后代。我们考察了在CFT和超引力侧扰动下的不破缺对称性，得到了相同的结果：（2，2）扰动下的N=（4，2）或N=（2，4）Poincaré超对称性和（1，1）扰动下的N=（0，4）或N=（4，0）超共形对称性.
Symmetry breaking by perturbations in the AdS/CFT correspondence is discussed. Perturbations of vector fields to the AdS3×S3solution of the six-dimensional N=(4,4) supergravity are considered. These perturbations are identified as descendents of chiral primary operators of a two-dimensional N=(4,4) CFT with conformal weight (2,2) or (1,1). We examine unbroken symmetries by the perturbations in the CFT side as well as in the supergravity side and find the same result: the N=(4,2) or N=(2,4) Poincaré supersymmetry for the (2,2) perturbation and the N=(0,4) or N=(4,0) superconformal symmetry for the (1,1) perturbation.
