标题： Peeling properties of lightlike signals in General Relativity

摘要： 研究了在一般Bondi-Sachs真空时空中传播并留下另一个Bondi-Sachs真空时空的类光信号的剥离性质。我们证明了一般情况下，剥离行为是与辐射孤立系统相关的传统行为，而如果类光信号历史两侧的渐近平坦时空在未来的null无穷远处比一般的Bondi-Sachs时空更快趋于平坦，则剥离行为会变得不寻常。这种情况发生在例如所讨论的时空是静态Bondi-Sachs时空时。 显示英文摘要

摘要： The peeling properties of a lightlike signal propagating through a general Bondi-Sachs vacuum spacetime and leaving behind another Bondi-Sachs vacuum space-time are studied. We demonstrate that in general the peeling behavior is the conventional one which is associated with a radiating isolated system and that it becomes unconventional if the asymptotically flat space-times on either side of the history of the light-like signal tend to flatness at future null infinity faster than the general Bondi-Sachs space-time. This latter situation occurs if, for example, the space-times in question are static Bondi-Sachs space- times.
