关于含陷阱面区域的边界

On the boundary of the region containing trapped surfaces

José M. M. Senovilla

摘要:

考虑了包含未来捕获闭曲面的时空区域的边界。在渐近平坦的时空中,这个边界不需要是事件视界,也不需要是动力学/捕获视界。分析了该边界的一些性质及其局部化,并举例说明。特别是,完全明确的未来陷入紧凑的表面渗透到平坦的Vaidya时空的一部分。

英文摘要:

The boundary of the region in spacetime containing future-trapped closed surfaces is considered. In asymptotically flat spacetimes, this boundary does not need to be the event horizon nor a dynamical/trapping horizon. Some properties of this boundary and its localization are analyzed, and illustrated with examples. In particular, fully explicit future-trapped compact surfaces penetrating into flat portions of a Vaidya spacetime are presented.
