我们描述的一般均匀平面波时空的渐近边界，使用的建设'点在无穷远'的因果结构的时空介绍了Geroch，Kronheimer和彭罗斯。我们表明，这种结构同意由Berenstein和Nastase获得的最大超对称的10维平面波的共形边界。我们详细地看到了超越（或围绕）无限的可能性是如何从光锥的结构中产生的。我们还讨论了扩展的建设时间依赖的平面波的解决方案，重点从DP膜的彭罗斯极限得到的例子。
We describe the asymptotic boundary of the general homogeneous plane wave spacetime, using a construction of the ‘points at infinity’ from the causal structure of the spacetime as introduced by Geroch, Kronheimer and Penrose. We show that this construction agrees with the conformal boundary obtained by Berenstein and Nastase for the maximally supersymmetric ten-dimensional plane wave. We see in detail how the possibility of going beyond (or around) infinity arises from the structure of light cones. We also discuss the extension of the construction to time-dependent plane wave solutions, focusing on the examples obtained from the Penrose limit of Dp-branes.
