Gauss-Bonnet-Yang-Mills引力的拓扑黑洞

Topological Black Holes of Gauss-Bonnet-Yang-Mills Gravity

M. H. Dehghani, N. Bostani, R. Pourhasan

摘要:

在规范半单群为$So(n(n-1)/2-1,1)$的非阿贝尔Yang-Mills场存在下,给出了具有双曲视界的Gauss-Bonnet引力的渐近AdS解.我们研究了这些解的性质,发现6维及更高维的非负质量解处处是实的,且具有类空奇点。它们提出了具有一个视界的黑洞,并具有与史瓦西时空相同的因果结构。5维的解或具有负质量的高维解并不是处处真实的。在这些情况下,需要进行转换以实现解决方案。这些解可能是裸奇点、极端黑洞、双视界黑洞或单视界黑洞。

英文摘要:

We present the asymptotically AdS solutions of Gauss-Bonnet gravity with hyperbolic horizon in the presence of a non-Abelian Yang-Mills field with the gauge semisimple group $So(n(n-1)/2-1,1)$. We investigate the properties of these solutions and find that the non-negative mass solutions in 6 and higher dimensions are real everywhere with spacelike singularities. They present black holes with one horizon and have the same causal structure as the Schwarzschild spacetime. The solutions in 5 dimensions or the solutions in higher dimensions with negative mass are not real everywhere. In these cases, one needs a transformation to make the solutions real. These solutions may present a naked singularity, an extreme black hole, a black hole with two horizons, or a black hole with one horizon.
