摘要:

令H为无限维复可分的Hilbert空间,H上有界线性算子的全体为B(H).用σ(T),σab(T)和σa(T)分别表示为算子T∈B(H)的谱集,Browder本质逼近点谱和逼近点谱.称算子T∈B(H)满足(R)性质,若σa(T)\σab(T)=π00(T),其中π00(T)={λ∈isoσ(T)∶0

Let H be an infinite dimensional separable complex Hilbert space and the totality of bounded operators on H is B(H).σ(T),σab(T)andσa(T)denote the spectrum,the Browder essential approximate spectrum and approximate point spectrum of T∈B(H)respectively.T∈B(H)satisfies the property(R)ifσa(T)\σab(T)=π00(T),whereπ00(T)={λ∈isoσ(T)∶0
