偶维小洛夫洛克黑洞的不稳定性

Instability of Small Lovelock Black Holes in Even-dimensions

Tomohiro Takahashi, Jiro Soda

摘要:

我们在爱因斯坦理论的高维推广Lovelock理论中研究静态黑洞的稳定性。本文导出了一般Lovelock理论中张量扰动的主方程。结果表明,所得方程的特征在于一个功能,它决定了背景黑洞解。这样,在一般维数下,静态黑洞在张量扰动作用下的稳定性问题就化为一个代数问题。我们表明,小洛夫洛克黑洞在偶数维是不稳定的。

英文摘要:

We study the stability of static black holes in Lovelock theory which is a natural higher dimensional generalization of Einstein theory. We derive a master equation for tensor perturbations in general Lovelock theory. It turns out that the resultant equation is characterized by one functional which determines the background black hole solutions. Thus, the stability issue of static black holes under tensor perturbations in general dimensions is reduced to an algebraic problem. We show that small Lovelock black holes in even-dimensions are unstable.
