一维周期势薛定谔方程的色散

Dispersion for Schrödinger equation with periodic potential in 1D

Scipio Cuccagna

摘要:

本文将Firsova证明的关于线性薛定谔方程解的色散的结果推广到一维光滑势无限多能带的情形。证明在于应用固定相稳定相位法。对相位的估计,基本上是带函数,来自Korotyaev的工作。大部分的文件是专门的Bloch函数的界限。对于这些界我们需要详细分析准动量函数和准动量函数的逆的一致化

英文摘要:

We extend a result on dispersion for solutions of the linear Schrödinger equation, proved by Firsova for operators with finitely many energy bands only, to the case of smooth potentials in 1D with infinitely many bands. The proof consists in an application of the method of stationary phase. Estimates for the phases, essentially the band functions, follow from work by Korotyaev. Most of the paper is devoted to bounds for the Bloch functions. For these bounds we need a detailed analysis of the quasimomentum function and the uniformization of the inverse of the quasimomentum function
