研究了AdS_3 × S^3 × S^3上的弦理论与具有大N=4超共形代数A_gamma的二维共形理论之间的对偶性.我们讨论的交叉膜的配置，产生这样的近地平线几何。我们计算的卡鲁扎-克莱因谱，并提出边界超共形理论可以描述一个合适的对称的产品空间与特定的选择反对称的两种形式的西格玛模型。
We study the duality between string theory on AdS_3 X S^3 X S^3 and two-dimensional conformal theories with large N=4 superconformal algebra A_gamma. We discuss configurations of intersecting branes which give rise to such near-horizon geometries. We compute the Kaluza-Klein spectrum and propose that the boundary superconformal theory can be described by a sigma model on a suitable symmetric product space with a particular choice of anti-symmetric two-form.
