| Abstract: | In this paper,we shall study a class of operators which is said to be(s,p)-w-hyponormal operators.Firstly,we shall give the character of(s,p)-w-hyponormal operators.Secondly,we show the inclusion relations of(s,p)-w-hyponormal operators.Thirdly,we show that the square of a special(s,p)-w-hyponormal operator is also(s,p)-w-hyponormal. |
