摘　　要：在左可逆算子性质的基础上利用Mbekhta子空间K(A)和H0(A)给出判定A为CI算子的充要条件及充分条件.丰富了CI算子理论,也扩充了K(A)和H0(A)的应用.This paper gives the necessary and sufficient The Department of Ma the matics, conditions of CI operator on the basis of Mbekhta＇ s subspaces and properties of left-invertible operator. These results not only enrich theories of CI operator but also enlarge the use of Mbekhta＇ s subspaces.

关 键 词：Mbekhta子空间 CI算子 左可逆算子
