摘要:

该文引入并研究了Banach空间中的有界线性算子的(h)性质,它是a-Weyl定理的推广.进而得到了(h)性质在有限秩和幂零扰动下的稳定性.单值扩张性是局部谱理论中的重要部分,该文还证明了(h)性质与单值扩张性之间的关系,从而得到了满足(h)性质的几类算子.

关键词: 单值扩张性, a-Weyl定理, (h)性质

Abstract:

In this paper, we introduce and study the property (h), which extends a-Weyl's theorem. We consider its stability under commuting finite rank and nilpotent perturbations. We prove that property (h) on Banach spaces is related to an important property which has a leading role in local spectral theory:the single-valued extension property. From this result we deduce that property (h) holds for several classes of operators.

Key words: Single-valued extension property, a-Weyl's theorem, Property (h)
