Pomeransky-Senkov黑洞的整体结构
On the global structure of the Pomeransky-Senkov black holes
摘要：
我们构造了具有多个Killing视界和渐近区域的Pomeransky-Senkov度量的解析扩展。我们表明，在我们的扩展，奇点相关的障碍，可微的度量在于超越事件视界。我们分析了非空奇异集的拓扑结构，它是参数依赖的。我们提出了稳定的因果关系的外部通信领域的数字证据。由此产生的全局结构有点让人想起克尔时空。
英文摘要：
We construct analytic extensions of the Pomeransky-Senkov metrics with multiple Killing horizons and asymptotic regions. We show that, in our extensions, the singularities associated to an obstruction to differentiability of the metric lie beyond event horizons. We analyze the topology of the non-empty singular set, which turns out to be parameter-dependent. We present numerical evidence for stable causality of the domain of outer communications. The resulting global structure is somewhat reminiscent of that of Kerr space-time.
