渐近圆柱端点流形上的正、逆散射

Forward and inverse scattering on manifolds with asymptotically cylindrical ends

Hiroshi Isozaki, Yaroslav Kurylev, Matti Lassas

摘要:

本文研究了非紧黎曼流形的反问题,其端点具有以下性质:在每一端,黎曼度量被假定为度量$(dy)^2 + h(x,dx)$形式的短程扰动,$h(x,dx)$是余维为1的紧致流形的度量。此外,一端是精确的圆柱形,即度量等于$(dy)^2 + h(x,dx)$。给定两个这样的流形具有相同的散射矩阵,完全圆柱形的所有能量结束,我们表明,这两个流形是等距的。

英文摘要:

We study an inverse problem for a non-compact Riemannian manifold whose ends have the following properties : On each end, the Riemannian metric is assumed to be a short-range perturbation of the metric of the form $(dy)^2 + h(x,dx)$, $h(x,dx)$ being the metric of some compact manifold of codimension 1. Moreover one end is exactly cylindrical, i.e. the metric is equal to $(dy)^2 + h(x,dx)$. Given two such manifolds having the same scattering matrix on that exactly cylindrical end for all energy, we show that these two manifolds are isometric.
