广义二维周期Dirac算子的特征值缺失

Absence of eigenvalues for the generalized two-dimensional periodic Dirac operator

L. I. Danilov

摘要:

考虑了一个广义二维周期Dirac算子,其一阶导数系数为$L^{\infty}$ -矩阵值,具有复矩阵值位势.证明了若矩阵值位势相对于自由Dirac算子有零界,则该算子的谱不含本征值。

英文摘要:

A generalized two-dimensional periodic Dirac operator is considered, with $L^{\infty}$-matrix-valued coefficients of the first order derivatives and with complex matrix-valued potential. It is proved that if the matrix-valued potential has zero bound relative to the free Dirac operator, then the spectrum of the operator in question contains no eigenvalues.
