一维纯Lovelock黑洞$d=3N+1$是稳定的

Pure Lovelock black hole in the dimension, $d=3N+1$, is stable

Radouane Gannouji, Yolbeiker Rodríguez Baez, Naresh Dadhich

摘要:

在本文中,我们表明,纯Lovelock静态Schwarzschild的类似物黑洞的尺寸$d>3N+1$,其中$N$是次数Lovelock多项式的作用,是稳定的,即使纯Gauss-Bonnet $N=2$黑洞是不稳定的尺寸$d<7$。我们还讨论和比较了同维纯Lovelock黑洞和相应的Einstein黑洞的准正规模。我们发现,扰动衰减的特征时间是弱的尺寸依赖,因为它只依赖于背景解决方案的引力势,而振荡的频率,但依赖于尺寸。我们还证明了除了$d=4$外,扰动谱不是等谱的.

英文摘要:

In this paper we show that pure Lovelock static Schwarzschild's analogue black hole in dimensions $d>3N+1$, where $N$ is the degree of Lovelock polynomial action, is stable even though pure Gauss-Bonnet $N=2$ black hole is unstable in dimension $d<7$. We also discuss and compare quasinormal modes for pure Lovelock and the corresponding Einstein black hole in the same dimension. We find that perturbations decay with characteristic time which is weakly dimensional dependent as it depends only on the gravitational potential of the background solution, while frequency of oscillations however depend on the dimension. Also we show that spectrum of perturbations is not isospectral except in $d=4$.
