n元胞势的离散谱

Discrete spectrum for n-cell potentials

Piotr G. Grinevich, Roman G. Novikov

摘要:

本文研究了具有$n$胞势的一维薛定谔方程的散射问题、Sturm-Liouville问题和具有周期或斜周期边界条件的谱问题.对于这些问题,我们给出了离散谱分布函数的上、下界。对于散射问题,我们给出,此外,明确的上限和下限的情况下,潜在的$n$不一定是相同的细胞组成的离散谱的分布函数。对于散射问题,得到了透射共振的一些结果。

英文摘要:

We study the scattering problem, the Sturm-Liouville problem and the spectral problem with periodic or skew-periodic boundary conditions for the one-dimensional Schrödinger equation with an $n$-cell (finite periodic) potential. We give explicit upper and lower bounds for the distribution functions of discrete spectrum for these problems. For the scattering problem we give, besides, explicit upper and lower bounds for the distribution function of discrete spectrum for the case of potential consisting of $n$ not necessarily identical cells. For the scattering problem some results about transmission resonances are obtained.
