Aretakis荷与渐近无穷大

Aretakis Charges and Asymptotic Null Infinity

Hadi Godazgar, Mahdi Godazgar, C. N. Pope

摘要:

本文建立了任意极端黑洞的阿雷塔基斯荷与Newman-Penrose荷之间的关系。这是通过在极端黑洞和我们所说的弱渐近平坦时空之间建立共形对应来实现的。在这种对应下,弱渐近平坦时空的纽曼-彭罗斯荷映射到极端黑洞的阿雷塔基斯荷上。此外,我们概括的极端Reissner-Nordström解决方案所显示的共形等距的一种新的共形对称性,一类静态STU超引力黑洞内的行为。

英文摘要:

We construct a relation between the Aretakis charge of any extreme black hole and the Newman-Penrose charge. This is achieved by constructing a conformal correspondence between extreme black holes and what we call weakly asymptotically flat space-times. Under this correspondence the Newman-Penrose charge of the weakly asymptotically flat space-time maps on to the Aretakis charge of the extreme black hole. Furthermore, we generalise the conformal isometry displayed by the extreme Reissner-Nordström solution to a novel conformal symmetry that acts within a class of static STU supergravity black holes.
