摘要:

本文研究了具有宇宙学常数和耦合到Gauss-Bonnet项的标量场的拓扑黑洞的微扰行为。本文用解析和数值方法计算了扩展标量张量高斯-邦纳引力中标量微扰的准正规模。在小黑洞的情况下,我们发现一个相变的拓扑黑洞的一个毛茸茸的配置。

英文摘要:

We study the perturbative behaviour of topological black holes in the presence of a cosmological constant and a scalar field coupled to the Gauss-Bonnet term. We calculate both analytically and numerically the quasi-normal modes of scalar perturbations in the extended scalar-tensor-Gauss-Bonnet gravity. In the case of small black holes we find a phase transition of the topological black hole to a hairy configuration.
