摘要 研究p 亚正规算子A∈B(H)的不变子空间约化A的充分条件,并证明了p 亚正规算子也具有Fuglede Putnam性质. The properties of phyponormal operators are studied, firstly, the sufficient condition of the invariant space of phyponormal operator A to reduce A is discussed; secondly, it is proved the FugledePutnam theorem property is owned by phyponormal operators.
