设T在希尔伯特空间H上为p-次正规或\rm{log}-次正规,则有XT=T^*X,当XT^*=TX时,对于scriptstyle{B}(\scriptstyle{H})中的某个X。这是Patel结果的延伸。同样对于p-次正态或\rm{log}-次正态T^*,主导S和任意在\scriptstyle{B}(\scriptstyle{H})中的X,使得XT=SX,我们有XT^*=S^*T。
Let T be p-hyponormal or \rm{log}-hyponormal on a Hilbert space H. Then we have XT=T^*X whenever XT^*=TX for some X \in \scriptstyle{B}(\scriptstyle{H}). This is an extension of Patel's result. Also for p-hyponormal or \rm{log}-hyponormal T^*, dominant S and any X \in \scriptstyle{B}(\scriptstyle{H}) such that XT=SX, we have XT^*=S^*T.
