视界检测与高维黑环

Horizon Detection and Higher Dimensional Black Rings

A. A. Coley, D. D. McNutt

摘要:

本文研究了五维旋转黑环和超对称黑环时空的定态视界。在旋转的黑环的情况下,我们使用Weyl对齐的零方向代数分类的Weyl张量,并利用适应的Cartan算法,以产生Cartan不变量。对于超对称黑环,我们采用判别方法,并重复适应的Cartan算法。对于这两个度量,我们能够构造仅检测视界的Cartan不变量,并且更容易计算和分析标量多项式曲率不变量。

英文摘要:

In this paper we study the stationary horizons of the rotating black ring and the supersymmetric black ring spacetimes in five dimensions. In the case of the rotating black ring we use Weyl aligned null directions to algebraically classify the Weyl tensor, and utilize an adapted Cartan algorithm in order to produce Cartan invariants. For the supersymmetric black ring we employ the discriminant approach and repeat the adapted Cartan algorithm. For both of these metrics we are able to construct Cartan invariants that detect the horizon alone, and which are easier to compute and analyse that scalar polynomial curvature invariants.
