黑洞内部弱零奇点的崩溃

人们普遍认为，一般的黑洞有一个非空但弱奇异的柯西视界，由于质量膨胀。事实上，这已经证明了作者在球形崩溃的收费标量场，根据衰变假设的领域在黑色的外部，这是apertured通用。于是一个自然的问题就产生了：这个弱奇异柯西视界是否能封闭时空，或者弱零奇点是否必然“崩溃”，让位于另一种类型的奇点？本文的主要结果是证明柯西视界永远不能“封闭”时空。因此，弱零奇点破裂并过渡到另一个奇点，其面积半径$r$扩展到$0$。
It is widely expected that generic black holes have a non-empty but weakly singular Cauchy horizon, due to mass inflation. Indeed this has been proven by the author in the spherical collapse of a charged scalar field, under decay assumptions of the field in the black exterior which are conjectured to be generic. A natural question then arises: can this weakly singular Cauchy horizon close off the space-time, or does the weak null singularity necessarily "break down", giving way to a different type of singularity? The main result of this paper is to prove that the Cauchy horizon cannot ever "close off" the space-time. As a consequence, the weak null singularity breaks down and transitions to a different singularity for which the area-radius $r$ extends to $0$.
