论文摘要
在经典的一般相对性的背景下，对定义旨在更广泛地适用的黑洞的新颖观点是在渐近平坦的空间之外进行的。该结构正式化了启发式观念，即黑洞是“过去的奇异事物的库奇发展”。因此，该公式以关键的方式取决于奇异性的识别，奇点已经通过各种边界结构在文献中进行了处理。尽管许多已知的边界结构（例如，施密特的B-BONDARY或GEROCH的G-BONDARY）可能被认为是一个人的黑洞概念，但众所周知的拓扑问题使我们对Scott和Szekeres的摘要的摘要的摘要提供了最自然的选择。该框架用于提出弱宇宙审查猜想的一般非IVP公式。
A novel perspective on defining black holes designed to be more broadly applicable outside of asymptotically flat spacetimes, in the context of classical general relativity, is presented, discussed, and characterized. The construction formalizes the heuristic idea that black holes are the "past Cauchy development of the set of singularities". As such, the formulation depends in a critical way on the identification of singularities, which has been treated in the literature through various boundary constructions. While many of the known boundary constructions (e.g. Schmidt's b-boundary or Geroch's g-boundary) could in principal be cited as underlying one's notion of a black hole, well-known topological concerns leads us to take the perspective that Scott and Szekeres' abstract boundary provides the most natural choice. The framework is utilized to put forward a general, non-IVP formulation of the Weak Cosmic Censorship Conjecture.
