视界相交和合并处的自相似临界几何
Self-similar critical geometries at horizon intersections and mergers
摘要：
我们研究高维黑洞解空间中的拓扑变化跃迁。Kol提出这些是由自相似双锥几何控制的锥型跃迁。我们提出了一个确切的例子，这种现象之间的交叉点的黑洞视界和宇宙学deSitter视界D >= 6。我们还描述了控制高维黑洞的相空间中的许多转变的临界几何的局部模型，例如拓扑球形黑洞到黑环或黑p球的捏缩，或者黑洞和黑土星中的黑环或D >= 6中的双环之间的合并。
英文摘要：
We study topology-changing transitions in the space of higher-dimensional black hole solutions. Kol has proposed that these are conifold-type transitions controlled by self-similar double-cone geometries. We present an exact example of this phenomenon in the intersection between a black hole horizon and a cosmological deSitter horizon in D >= 6. We also describe local models for the critical geometries that control many transitions in the phase space of higher-dimensional black holes, such as the pinch-down of a topologically spherical black hole to a black ring or to a black p-sphere, or the merger between black holes and black rings in black Saturns or di-rings in D >= 6.
