论文摘要
最近有人认为，对称Orbifold理论的大$ n $限制具有$ \ m athfrak {sl} {2，\ mathbb {r}）$ wzw模型的广告/CFT双重世界表描述。在先前的工作中，确定了与对称的Orbifold应力能量张量相对应的世界表状态。我们计算了世界表上相应的顶点操作员的某些2和3点函数，并证明这些振幅从双重对称的Orbifold透视图中重现了人们的期望。
The large $N$ limit of symmetric orbifold theories was recently argued to have an AdS/CFT dual world-sheet description in terms of an $\mathfrak{sl}(2,\mathbb{R})$ WZW model. In previous work the world-sheet state corresponding to the symmetric orbifold stress-energy tensor was identified. We calculate certain 2- and 3-point functions of the corresponding vertex operator on the world-sheet, and demonstrate that these amplitudes reproduce exactly what one expects from the dual symmetric orbifold perspective.
