Abstract

In this paper, we study the direct scattering problem on the half-line for the Dirac system of differential equations in the case of finite density with the boundary condition \(y_{1}(0)=y_{2}(0) \). The spectrum is studied, the resolvent is constructed, and the spectral expansion in the eigenfunctions of the Dirac operator is obtained.

有限密度情况下半线上狄拉克微分方程系统的直接散射理论问题
摘要 本文研究了在有限密度情况下,边界条件为 \(y_{1}(0)=y_{2}(0) \)的狄拉克微分方程系统在半线上的直接散射问题。研究了频谱,构建了解析力,并得到了狄拉克算子特征函数的频谱展开。
