两个5膜与一根弦的非标准相交可以得到AdS3 × S3 × S3 × S1。我们考虑了这种几何结构的Penrose极限，并研究了得到的pp波解的超对称性。在两个3球内，两个叶理圆的正交旋转存在一个单参数的Penrose极限族。只有当旋转角度为45°时才会出现多余的消旋量，在这种情况下，我们得到了相应的具有线性实现超对称的光锥弦作用。我们还得到了AdS3或AdS2与2球积的其他非标准交点的Penrose极限。产生的pp波由多个恒定场强支撑。
The non-standard intersection of two 5-branes and a string can give rise to AdS3 × S3 × S3 × S1. We consider the Penrose limit of this geometry and study the supersymmetry of the resulting pp-wave solution. There is a one-parameter family of Penrose limits associated with the orthogonal rotation of the two foliating circles within the two 3-spheres. Supernumerary Killing spinors arise only when the rotation angle is 45°, for which case we obtain the corresponding light-cone string action that has linearly-realized supersymmetry. We also obtain Penrose limits of other non-standard intersections that give rise to the product of AdS3 or AdS2 and 2-spheres. The resulting pp-waves are supported by multiple constant field strengths.
