张量值波在渐近Kerr-de Sitter空间上的共振展开

Resonance expansions for tensor-valued waves on asymptotically Kerr-de Sitter spaces

Peter Hintz

摘要:

在最近与Vasy的合作工作中,我们分析了黑洞时空中微分形式值波的低能行为。为了推导出渐近性和衰减,人们还需要对作用于形式丛截面上的波算子进行高能量估计。本文提供了这些在所有时空维度$n\geq 4$的Schwarzschild-de Sitter空间的扰动。事实上,我们证明了指数衰减,直到一个有限维空间的共振,波值在任何有限秩子丛的张量丛,其中特别包括微分形式和对称张量。作为研究不具有自然正定内积的向量丛的主要技术工具,我们引入了伪微分内积,它是依赖于在相空间中的位置的内积。

英文摘要:

In recent joint work with Vasy, we analyze the low energy behavior of differential form-valued waves on black hole spacetimes. In order to deduce asymptotics and decay from this, one in addition needs high energy estimates for the wave operator acting on sections of the form bundle. The present paper provides these on perturbations of Schwarzschild-de Sitter spaces in all spacetime dimensions $n\geq 4$. In fact, we prove exponential decay, up to a finite-dimensional space of resonances, of waves valued in any finite rank subbundle of the tensor bundle, which in particular includes differential forms and symmetric tensors. As the main technical tool for working on vector bundles that do not have a natural positive definite inner product, we introduce pseudodifferential inner products, which are inner products depending on the position in phase space.
