被困面

Trapped surfaces

José M. M. Senovilla

摘要:

我回顾的定义和类型的(封闭的)捕获表面。令人惊讶的全局属性显示,如他们的“千里眼”和他们进入时空的平坦部分的可能性。给出了捕获曲面与向量场和空间超曲面相互作用的几个结果。应用准本地定义的黑洞进行了讨论,特别强调设置到边缘捕获管,捕获地平线和边界的封闭捕获表面的区域。最后介绍了俘获区的核心,并讨论了它的重要性。

英文摘要:

I review the definition and types of (closed) trapped surfaces. Surprising global properties are shown, such as their "clairvoyance" and the possibility that they enter into flat portions of the spacetime. Several results on the interplay of trapped surfaces with vector fields and with spatial hypersurfaces are presented. Applications to the quasi-local definition of Black Holes are discussed, with particular emphasis set onto marginally trapped tubes, trapping horizons and the boundary of the region with closed trapped surfaces. Finally, the core of a trapped region is introduced, and its importance discussed.
