摘要 研究了一类无穷维Hamilton算子的本质谱.通过算子矩阵内部元素的本质谱给出了整体算子矩阵本质谱的刻画。基于以上结论,分别给出由板弯曲方程和梁弯曲方程导出的无穷维Hamilton算子的谱性质. In this paper,the essential spectrum for a class of infinite dimensional Hamiltonian operator is studied.A description of the essential spectra for operator matrices is given by using the essential spectra for entries of this operator matrices.Based on this results,spectral properties of infinite dimensional Hamiltonian operators associated with plate bending equations and beam bending equations are obtained,respectively.
