论文摘要
在空间时间中，考虑到penrose限制，在真空中以及在存在电磁场的情况下，承认两个Abelian，类似太空的杀伤向量。这种类型的空间时间描述了不均匀的宇宙学以及碰撞平面引力和电磁波。在TOD [1]的工作之后，在这些背景下研究了对角penrose限制的条件。在Penrose极限中给出的这些空间时间和解决方案中，考虑了曲折方程。
Penrose limits are considered in space-times admitting two abelian, space-like Killing vectors in vacuum as well as in the presence of an electromagnetic field. This type of space-times describe inhomogeneous cosmologies as well as colliding plane gravitational and electromagnetic waves. Following the work of Tod [1] the conditions for diagonal Penrose limits are investigated in these backgrounds. The twistor equation is considered in these space-times and solutions given in the Penrose limit.
