摘要
研究了希尔伯特空间上算子束的特性.利用算子谱理论及空间分解的技巧,通过构造算子矩阵的方法,得到线性算子束Aλ+B谱的性质及Aλ+B的非正规性的充分必要条件.
Let be separable Hilbert spaces and (A,B) be a given pair of operators in B() . Some properties of the spectrum σ(λA+B) of λA+B is considered and the necessary and suffi- cient conditions have been obtained for Aλ +B to be non-regular by using the method of block operator construction and the theory of operator spectrum.
