跳跃边界扩散的谱分析

Spectral Analysis of Diffusions with Jump Boundary

Martin Kolb, Achim Wübker

摘要:

本文研究了具有跳跃边界和确定性跳跃分布的有限区间上的一维常系数扩散问题。我们使用耦合的方法,以确定在一个大的漂移的情况下的光谱间隙,并证明,有一个阈值漂移以上的频谱的底部不再依赖于漂移。作为推论,我们的结果,我们能够回答两个问题有关椭圆本征值问题与非局部边界条件制定以前由Iddo Ben-Ari和Ross Pinsky。

英文摘要:

In this paper we consider one-dimensional diffusions with constant coefficients in a finite interval with jump boundary and a certain deterministic jump distribution. We use coupling methods in order to identify the spectral gap in the case of a large drift and prove that that there is a threshold drift above which the bottom of the spectrum no longer depends on the drift. As a Corollary to our result we are able to answer two questions concerning elliptic eigenvalue problems with non-local boundary conditions formulated previously by Iddo Ben-Ari and Ross Pinsky.
