摘要
根据一致Fredholm指标性质定义一种新的谱集,利用该谱集与Browder谱之间的关系给出Hilbert空间中有界线性算子满足(ω)性质的充要条件,并刻画多项式函数的(ω)性质.
According to the property of consistence in Fredholm index,a new spectral set was defined.By using the relationship between the spectral set and Browder spectrum,the author gave the necessary and sufficient conditions for a bounded linear operator on a Hilbert space to satisfy the property(ω),and characterized the property(ω)of polynomial functions.
