Gustav Holzegel, Georgios Mavrogiannis, Renato Velozo Ruiz

AI总结:

本文提出新型全局物理空间乘子,为 Schwarzschild、极端 Reissner–Nordström 和 Schwarzschild–de Sitter 时空中的积分局部能量衰减估计提供简洁证明。

摘要:

我们给出了 Schwarzschild、极端 Reissner–Nordström 和 Schwarzschild–de Sitter 时空上积分局部能量衰减估计的简短证明。这些证明采用新颖的全局物理空间乘子;除了显著的简洁性之外,它们:(a) 可直接由测地流导出,(b) 不需要分解为球谐函数,并且 (c) 其边界项仅由守恒的 $T$-能量即可控制。我们还阐述了本文乘子与前两位作者引入的全局良好交换子之间的密切联系。

英文摘要:

We present short proofs of integrated local energy decay estimates on Schwarzschild, extremal Reissner-Nordström, and Schwarzschild-de Sitter spacetimes. The proofs employ novel global physical space multipliers, which, besides their remarkable simplicity, (a) are directly derivable from the geodesic flow, (b) do not require decomposition into spherical harmonics, and (c) whose boundary terms can be controlled by the conserved $T$-energy alone. We also elaborate on the intimate connection between the multipliers of the present paper and the globally good commutators introduced by the first two authors.
