从AdS/CFT对应的整体观点出发，研究了插入具有大R荷J的局部算子Z^J和Zbar^J的Wilson环算子的期望值。古典解决方案的字符串附加到这样的变形威尔逊环在共形边界的构造和威尔逊环的期望值的计算。我们认为，为了有这样的解决方案，一般插入在有限的位置在基本时空的规范理论，这是至关重要的解释全息对应的半经典图片作为一个隧道现象，已经建立了全息计算的BMN运营商。这也需要使用欧几里德化的AdS背景和欧几里德超杨-米尔斯理论。
We study the expectation values of Wilson-loop operators with the insertionsof local operators Z^J and Zbar^J with large R-charge J from the bulk viewpoint of AdS/CFT correspondence. Classical solutions of strings attached to such deformed Wilson loops at the conformal boundary are constructed and are applied to the computation of Wilson-loop expectation values. We argue that in order to have such solutions for general insertions at finite positions in the base spacetime of the gauge theory, it is crucial to interpret the holographic correspondence in the semi-classical picture as a tunneling phenomenon, as has been previously established for holographic computations of correlators of BMN operators. This also requires to use the Euclideanized AdS background and Euclidean super Yang-Mills theory.
