渐近双曲空间和Kerr-de Sitter空间的微局部分析

Microlocal analysis of asymptotically hyperbolic and Kerr-de Sitter spaces

Andras Vasy, Semyon Dyatlov

摘要:

在本文中,我们开发了一个一般的,系统的,微局部框架的Fredholm分析的非椭圆问题,包括高能量(或半经典)的估计,这是稳定的扰动。考虑到现代微局部分析,这个框架相对简单,在符号陈述之后只需要十几页。它位于一个没有边界的紧致流形上,因此在微局部分析的标准设置中,包括半经典分析。本文的其余部分致力于应用。许多自然的应用出现在设置非黎曼b-度量的背景下梅尔罗斯的b-结构。这些度量包括渐近Minkowski度量、自然紧化爆破上的渐近de Sitter型度量和Kerr-de Sitter型度量。然而,最简单的应用是提供一种新的方法来分析黎曼或洛伦兹(或者实际上,可能是其他签名)共形紧空间(如渐近双曲或de Sitter空间)。结果包括,特别是,一个新的建设的亚纯扩展的拉普拉斯算子在黎曼的情况下,以及高能量估计的谱参数条的复平面。Dyatlov在附录中将他对精确Kerr-de Sitter空间上的共振分析(然后用于分析该设置中的波动方程)与这里描述的更一般的方法联系起来。

英文摘要:

In this paper we develop a general, systematic, microlocal framework for the Fredholm analysis of non-elliptic problems, including high energy (or semiclassical) estimates, which is stable under perturbations. This framework is relatively simple given modern microlocal analysis, and only takes a bit over a dozen pages after the statement of notation. It resides on a compact manifold without boundary, hence in the standard setting of microlocal analysis, including semiclassical analysis. The rest of the paper is devoted to applications. Many natural applications arise in the setting of non-Riemannian b-metrics in the context of Melrose's b-structures. These include asymptotically Minkowski metrics, asymptotically de Sitter-type metrics on a blow-up of the natural compactification and Kerr-de Sitter-type metrics. The simplest application, however, is to provide a new approach to analysis on Riemannian or Lorentzian (or indeed, possibly of other signature) conformally compact spaces (such as asymptotically hyperbolic or de Sitter spaces). The results include, in particular, a new construction of the meromorphic extension of the resolvent of the Laplacian in the Riemannian case, as well as high energy estimates for the spectral parameter in strips of the complex plane. The appendix written by Dyatlov relates his analysis of resonances on exact Kerr-de Sitter space (which then was used to analyze the wave equation in that setting) to the more general method described here.
