摘要
利用分析和算子的方法研究具有可积复系数的高阶J-自伴微分算子的本质谱,得到这类算子的本质谱分布情况.
By using the method of analysis and operator,the essential spectrum of high-order J-self-adjoin differential operators with integral complex coefficient was investigated and the spectrum distribution mode of this class of operators was obtained.
