摘要
(ω′)性质与广义(ω′)性质是Weyl定理的变形.研究了Hilbert空间上有界线性算子T及其T的演算有广义(ω′)性质的充要条件,然后利用所得的结论研究了控制类算子有广义(ω′)性质的充要条件.
The property (ω′) and the generalized property (ω′) are variants of Weyl's theorem. For a bounded linear operator T acting on a Hilbert space, we establish for T and the calculus of T the sufficient and necessary conditions for which the generalized property (ω′) holds, also the class of dominant operaters having been considered.
