在一般旋转黑洞内部形成弱null奇点

The formation of a weak null singularity in the interior of generic rotating black holes

Stanford University(斯坦福大学);University of Edinburgh(爱丁堡大学)

Jonathan Luk, Jan Sbierski

AI总结:

研究证明在特定初始值问题中,黑洞最终趋于Kerr态时会形成弱null奇点,时空度规可连续延拓但不可Lipschitz延拓,核心方法是稳定性论证。

摘要:

给定一个特征初始值问题,其光滑数据代表一个动态的事件视皮层在亚极端、严格旋转范围内趋于Kerr态,我们证明在该奇点处形成弱null奇点,该奇点跨过时,时空度规可连续延拓但不可Lipschitz延拓。证明的主要部分是一个稳定性论证,显示动态Teukolsky场可被线性Teukolsky场近似,而线性不稳定性的证明已在先前工作中完成。

英文摘要:

Given a characteristic initial value problem with smooth data representing a dynamical event horizon settling down to that of Kerr in the subextremal, strictly rotating range with suitable upper and lower bounds, we prove that a weak null singularity forms, across which the spacetime metric is continuously extendible but not Lipschitz extendible. The bulk of the proof is a stability argument showing that a dynamical Teukolsky field can be approximated by a linear Teukolsky field, whose linear instability was proved in previous works.
