Kerr-de Sitter黑洞的准正规模和能量指数衰减

Quasi-normal modes and exponential energy decay for the Kerr-de Sitter black hole

Semyon Dyatlov

摘要:

本文给出了旋转黑洞准正规模的严格定义。它们是由某个亚纯算子族的极点给出的,并且与物理文献中的启发式定义一致。如果黑洞旋转足够慢,我们表明,这些极点形成一个离散的子集的复平面。作为一个应用,我们证明了线性波的本地能量在该背景下指数衰减一旦正交于零共振。

英文摘要:

We provide a rigorous definition of quasi-normal modes for a rotating black hole. They are given by the poles of a certain meromorphic family of operators and agree with the heuristic definition in the physics literature. If the black hole rotates slowly enough, we show that these poles form a discrete subset of the complex plane. As an application we prove that the local energy of linear waves in that background decays exponentially once orthogonality to the zero resonance is imposed.
