摘要
主要讨论具有周期复系数的二阶非自伴微分算子的谱,通过分析二阶周期复系数微分方程的解的结构,给出了由周期复系数的二阶微分算式所生成的J-自伴算子的谱是纯连续谱.
The spectra of periodic complex coefficients of the second-order non-self-adjoint differential operator were considered.Through the analysis of a solution in the form of the second order self-adjoint operator,the fact that its spectrum is purely continuous was proven.
