论文摘要
我们在$ \ text {ads} _3 $上考虑了由kalb-ramond Flux支持的Bosonic String理论。众所周知，$α'$精确的世界表格理论是由$ \ text {sl（2，r）} $ WZW模型描述的。在本说明中，我们对[arxiv：2104.07233]中提出的$α'$精确双重描述进行检查，该描述涉及自由理论背景上的绕组冷凝物。我们为双重性的两侧提供了顶点算子的明确图，并通过直接计算证明了其两个和三个点函数的等效性。二元性具有$α'$的强大性质。
We consider bosonic string theory on $\text{AdS}_3$ supported by Kalb-Ramond flux. It is well known that the $α'$ exact worldsheet theory is described by the $\text{SL(2,R)}$ WZW model. In this note we perform checks of an $α'$ exact dual description proposed in [arXiv:2104.07233] involving a winding condensate on a free theory background. We give the explicit map of vertex operators for normalizable states on both sides of the duality and demonstrate the equivalence of their two and three point functions by direct computation. The duality is of strong-weak nature in $α'$.
