极端Kerr喉中的非动力学

No Dynamics in the Extremal Kerr Throat

Aaron J. Amsel, Gary T. Horowitz, Donald Marolf, Matthew M. Roberts

摘要:

受Kerr/CFT猜想的启发,我们探索真空广义相对论的解,其渐近行为与极端Kerr喉(有时称为近视界极端Kerr(NHEK)几何)的渐近行为一致。我们认为,所有这样的解决方案都是同构的NHEK几何本身。逻辑分两步进行。我们首先认为,某些费用必须消失在任何时候的任何解决方案与NHEK渐近。然后,我们详细分析这些费用的线性化解决方案。虽然人们可以选择相关的电荷在任何初始时刻消失,但这些电荷并不守恒。因此,要求电荷在任何时候都消失是一个强得多的条件。我们认为,所有满足这个条件的解决方案是NHEK度量的同构。

英文摘要:

Motivated by the Kerr/CFT conjecture, we explore solutions of vacuum general relativity whose asymptotic behavior agrees with that of the extremal Kerr throat, sometimes called the Near-Horizon Extreme Kerr (NHEK) geometry. We argue that all such solutions are diffeomorphic to the NHEK geometry itself. The logic proceeds in two steps. We first argue that certain charges must vanish at all times for any solution with NHEK asymptotics. We then analyze these charges in detail for linearized solutions. Though one can choose the relevant charges to vanish at any initial time, these charges are not conserved. As a result, requiring the charges to vanish at all times is a much stronger condition. We argue that all solutions satisfying this condition are diffeomorphic to the NHEK metric.
