慢转动Kerr-de Sitter族的线性稳定性

Linear stability of the slowly-rotating Kerr-de Sitter family

Allen Juntao Fang

摘要:

本文证明了慢转Kerr-de Sitter黑洞族作为含$Λ>0$谐波规范的Einstein真空方程的一族解是线性稳定的.这篇文章是一系列文章的一部分,该系列文章提供了慢旋转的Kerr-de Sitter家族的完全非线性稳定性的新证明。本文及其后续工作提供了一个自包含的替代方法,从原来的工作Hintz和Vasy的非线性稳定性的Kerr-de Sitter家庭通过解释准正规模式的$H^k$特征值的运营商在希尔伯特空间,并使用集成的本地能量衰减估计证明存在的谱隙。特别是,我们避免了亚纯延续的预解式的建设。我们也不紧化时空,从而避免使用$b$ -演算,而是只使用标准的伪微分参数在附近的陷阱集,并避免约束阻尼。本文中的方法提供了一个明确的例子,说明如何使用向量场方法来实现陷阱背景下的预解估计。

英文摘要:

In this paper, we prove that the slowly-rotating Kerr-de Sitter family of black holes are linearly stable as a family of solutions to the Einstein vacuum equations with $Λ>0$ in harmonic (wave) gauge. This article is part of a series that provides a novel proof of the full nonlinear stability of the slowly-rotating Kerr-de Sitter family. This paper and its follow-up offer a self-contained alternative approach to nonlinear stability of the Kerr-de Sitter family from the original work of Hintz and Vasy by interpreting quasinormal modes as $H^k$ eigenvalues of an operator on a Hilbert space, and using integrated local energy decay estimates to prove the existence of a spectral gap. In particular, we avoid the construction of a meromorphic continuation of the resolvent. We also do not compactify the spacetime, thus avoiding the use of $b$-calculus and instead only use standard pseudo-differential arguments in a neighborhood of the trapped set; and avoid constraint damping altogether. The methods in the current paper offer an explicit example of how to use the vectorfield method to achieve resolvent estimates on a trapping background.
