薛定谔方程II解的解析波前集--长程扰动

Analytic Wave Front Set for Solutions to Schrödinger Equations II -- Long Range Perturbations

Andre' Martinez, Shu Nakamura, Vania Sordoni

摘要:

本文是作者arXiv:0706.0415的一篇论文的继续,其中考虑了平坦欧几里得度量的短程扰动。在这里,我们推广的文件的结果,以远程扰动(特别是,我们可以允许潜在的增长像$<x>^{2-\varepsilon}$在无穷大)。更准确地说,我们构建了一个修改后的量子自由演化$G_0(-s, hD_z)$作用于Sjöstrand的空间,我们描述了解析波前集的解$e^{-itH}u_0$的薛定谔方程,在半经典指数衰减的$G_0(-th^{-1}, hD_z)T u_0$,其中$T$代表巴格曼变换。该结果对前向非陷阱点附近的$t<0$和后向非陷阱点附近的$t>0$都是有效的。它是Nakamura(arXiv:math/0605742)的论文对分析框架的扩展。

英文摘要:

This paper is a continuation of a paper by the authors: arXiv:0706.0415, where short range perturbations of the flat Euclidian metric where considered. Here, we generalize the results of the paper to long-range perturbations (in particular, we can allow potentials growing like $<x>^{2-\varepsilon}$ at infinity). More precisely, we construct a modified quantum free evolution $G_0(-s, hD_z)$ acting on Sjöstrand's spaces, and we characterize the analytic wave front set of the solution $e^{-itH}u_0$ of the Schrödinger equation, in terms of the semiclassical exponential decay of $G_0(-th^{-1}, hD_z)T u_0$, where $T$ stands for the Bargmann-transform. The result is valid for $t<0$ near the forward non trapping points, and for $t>0$ near the backward non trapping points. It is an extension of a paper by Nakamura (arXiv:math/0605742) to the analytic framework.
