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.

关键词: (ω)性质, 一致Fredholm指标, 谱

Abstract: 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.

Key words: property (ω), consistence in Fredholm index (CFI), spectrum
