In addition,we show that Weyl s theorem holds for analytically M-hyponormal operators andα-Weyl s theorem holds for analytically cohyponormal operators.
若T有单值延伸性且T为reguloid算子,则Weyl定理对f(T)成立,其中f∈H(σ(T)),而当T~*有单值延伸性且T是reguloid算子,α-Weyl定理对f(T)成立,其中,f∈H(σ(T)),作为定理应用,我们证明了Weyl定理对解析M-亚正规算子成立,α-Weyl定理对解析余亚正规算子成立。
