摘要
本文利用拓扑一致降标研究了Weyl定理的两个变形——广义(ω_1)性质及广义(ω)性质,给出了Hilbert空间中有界线性算子满足广义(ω_1)性质及广义(ω)性质的充要条件;最后,利用所得结果讨论了2×2上三角算子矩阵的广义(ω_1)性质及广义(ω)性质.
In this paper we study the generalized property (w1) and generalized property (w) which are two variants of Weyl's theorem by means of the topological uniform descent, and establish for a bounded linear operator defined on a Hilbert space the sufficient and necessary conditions for which generalized property (wl) and generalized property (w) hold. In addition, the generalized property (w1) and generalized property (w) for 2 × 2 upper triangular operator matrices are discussed.
