高维球对称黑洞的IDEAL刻画

IDEAL characterization of higher dimensional spherically symmetric black holes

Igor Khavkine

摘要:

在广义相对论中,一个参考时空度规$g_0$的IDEAL(Intrinsic,Deductive,Explicit,ALtassimic)表征由一组张量方程$T[g]=0$组成,由度规$g$、其黎曼曲率及其导数协变构造,当且仅当$g$与参考时空度规$g_0$局部等距时满足。我们给出了广义Schwarzschild-Tangherlini时空的第一个理想特征,它由高维球对称黑洞的$Λ$ -真空扩展组成,以及它们的版本,其中球被平坦或双曲空间所取代。标准史瓦西黑洞在费兰多和赛斯的工作中已经被描述过了,但是他们使用的是高度特定于$4$维度的方法。专门为$4$尺寸,我们的结果提供了一个独立的,替代的表征。我们还证明了一个版本的Birkhoff定理,也适用于邻域的地平线和地平线分歧点,这是必要的,我们的论点。

英文摘要:

In general relativity, an IDEAL (Intrinsic, Deductive, Explicit, ALgorithmic) characterization of a reference spacetime metric $g_0$ consists of a set of tensorial equations $T[g]=0$, constructed covariantly out of the metric $g$, its Riemann curvature and their derivatives, that are satisfied if and only if $g$ is locally isometric to the reference spacetime metric $g_0$. We give the first IDEAL characterization of generalized Schwarzschild-Tangherlini spacetimes, which consist of $Λ$-vacuum extensions of higher dimensional spherically symmetric black holes, as well as their versions where spheres are replaced by flat or hyperbolic spaces. The standard Schwarzschild black hole has been previously characterized in the work of Ferrando and Sáez, but using methods highly specific to $4$ dimensions. Specialized to $4$ dimensions, our result provides an independent, alternative characterization. We also give a proof of a version of Birkhoff's theorem that is applicable also on neighborhoods of horizon and horizon bifurcation points, which is necessary for our arguments.
