| Abstract: | In this paper, some problems on M-hyponormal operators are discussed. A nece-ssary and sufficient condition for T to be an M-hyponormal operator is obtained. IfT is an M-hyponormal operator, then it is proved that a special class of functionaltransformations keeps spectral mapping.This paper also gives some conditions un-der which operator T is a normal operator. |
