球形引力塌缩中的前兆奇点。

本文给出了在球形引力坍缩中形成裸壳聚焦奇点的一般条件。这些奇点之所以赤裸，是因为在真正的引力奇点出现之前，引力势不是单值的。有人认为，它们并不违反宇宙审查的精神。相反，它们很可能是相对论引力坍缩的一个基本的一般特征。
General conditions are developed for the formation of naked precursory (``shell-focusing') singularities in spherical gravitational collapse. These singularities owe their nakedness to the fact that the gravitational potential fails to be single valued prior to the onset of a true gravitational singularity. It is argued that they do not violate the spirit of cosmic censorship. Rather, they may well be an essentially generic feature of relativistic gravitational collapse.
