Miguel Ballesteros, Gerardo Franco Córdova, Guillermo Garro, Hermann Schulz-Baldes

摘要:

本文研究了具有有限一阶矩的矩阵势的一维矩阵薛定谔算子的散射理论。透射系数的解析连续和扩展到带边。给出了这些扩张的显式表达式。计算了带边反射系数的极限。

英文摘要:

This paper is about the scattering theory for one-dimensional matrix Schrödinger operators with a matrix potential having a finite first moment. The transmission coefficients are analytically continued and extended to the band edges. An explicit expression is given for these extensions. The limits of the reflection coefficients at the band edges is also calculated.
