摘要 设T=(A B0 JA*J)∈B(H⊕H),其中A,B∈B(H),共轭变换J为H上满足J2=I且任给x,y∈H,都有〈Jx,Jy〉=〈y,x〉的反线性映射。研究了算子矩阵T的单值扩张性质以及Browder定理在紧摄动下的稳定性。 Let T=(A,B,0,JA*J)∈B(H⊕H), where A,B∈B(H), conjugation J is an antilinear operator on H, which satisfies J2 =I and 〈Jx,Jy〉=〈y,x〉 for all x,y∈H. The stability of the single valued extension property and the Brow-der’ s theorem for T under compact perturbations are explored.
