论文摘要
我们在ADS上的特殊限制的旧结果和最新结果与纯NS-NS通量：字符串长度$ \ ell_s = \ sqrt {α'} $等于ADS $ _3 $ RADIUS $ R $的极限。在模量空间的这一点上，该理论表现出特殊的特性，我们将讨论。特别注意与边界CFT目标空间的非紧凑性相关的相关函数的特征，以及当接近点$ k \ equiv r^2/α'= 1 $时，这些特征如何变化。此外，我们简要回顾了最新的建议，以实现此特殊点的ADS/CFT通信的确切实现。 \ [\]这是作者在Southern Cone会议上的8 $^{\ text {th}} $版本上发表的谈话的笔录，该量子重力在南锥会议上，在巴塔哥尼亚举行，12月16日，12月16日$^{\ text {tht}} $ - 20 $ - 20 $^{\ text {\ text {text}} $，2019年。
We review old and recent results on a special limit of string theory on AdS$_3\times M_7$ with pure NS-NS fluxes: the limit in which the string length $\ell_s=\sqrt{α'}$ equals the AdS$_3$ radius $R $. At this point of the moduli space, the theory exhibits special properties, which we discuss. Special attention is focused on features of correlation functions that are related to the non-compactness of the boundary CFT target space, and on how these features change when the point $k\equiv R^2/α' =1$ is approached. Also, we briefly review recent proposals for exact realizations of AdS/CFT correspondence at this special point. \[\] This is the transcript of the talk delivered by the author at the 8$^{\text{th}}$ edition of the Quantum Gravity in the Southern Cone conference, held in Patagonia, December 16$^{\text{th}}$ - 20$^{\text{th}}$, 2019.
