摘要
研究了斜对角块算子矩阵H=(0BC0)的本质谱.通过算子矩阵内部元素B和C的乘积算子的本质谱给出了整体算子矩阵本质谱的刻画.作为应用,研究了矩形板弯曲方程导出的无穷维Hamilton算子的本质谱.
Essential spectrum of off-diagonal operator matrices of the form H = 〔0 B C 0〕 is stud ied. A connection is estabtished between the essential spectrum of the product operators of H＇s inner elements B and C and the essential spectrum of H. As an application, the essential spectrum of Hamiltonian operator matrix which is derived from the plate bending equation is discussed.
