渐近双曲空间的微局部分析及高能量预解式估计

Microlocal analysis of asymptotically hyperbolic spaces and high energy resolvent estimates

Andras Vasy

摘要:

本文给出了作者最近提出的一种分析渐近双曲空间上拉普拉斯算子的新方法。这种新方法特别构造了偶度量(在Guillarmou意义下)预解式的解析延拓,并给出了高能量的条估计。关键的想法是一个扩展的边界上的一个问题,从拉普拉斯变换的频谱参数。扩展的问题是非椭圆的-事实上,在另一方面,它与渐近de Sitter空间上的Klein-Gordon方程有关-但尽管如此,它可以通过Fredholm理论的方法进行分析。这种方法是分析偏微分方程的更一般方法的一个特例,其中包括例如Kerr-de Sitter和Minkowski型空间。本文件是独立的,并处理渐近双曲空间没有负担的读者只需要的材料分析的洛伦兹问题考虑在作者的原始工作。

英文摘要:

In this paper we describe a new method for analyzing the Laplacian on asymptotically hyperbolic spaces, which was introduced recently by the author. This new method in particular constructs the analytic continuation of the resolvent for even metrics (in the sense of Guillarmou), and gives high energy estimates in strips. The key idea is an extension across the boundary for a problem obtained from the Laplacian shifted by the spectral parameter. The extended problem is non-elliptic -- indeed, on the other side it is related to the Klein-Gordon equation on an asymptotically de Sitter space -- but nonetheless it can be analyzed by methods of Fredholm theory. This method is a special case of a more general approach to the analysis of PDEs which includes, for instance, Kerr-de Sitter and Minkowski type spaces. The present paper is self-contained, and deals with asymptotically hyperbolic spaces without burdening the reader with material only needed for the analysis of the Lorentzian problems considered in the author's original work.
