一类本质正规算子的稳定不变子空间
The Stable Invariant Subspace of Certain Essentially Normal Operators
摘要
Abstract
In this paper, we give the character of stable invariant subspace of certain essentially normal operators, i.e, T∈L(H2(Ω;μ)) and T satisfies the following conditions ① T is an essentially normal; ② σ(T)=Ω,σc(T)=Ω,σp(T)=Ω; ③ind(T z)=n, z∈Ω; ④minind(T z)=0, z∈Ω. IfMisanontrivial invariant subspace of T, then M is a stable invariant subspace of T if and only if dimM<∞ and dimM⊥ = ∞.关键词
