operators. In this paper, we give an extension of this notion of supraposinormality to α-supraposinormality of operators in the densenorm-attainableclass. … In this paper, we are interested in characterizing α−supraposinormaloperators in densenorm-attainableclasses. At this point, we give some useful notations. From [1] it is known that an …
The notion of supraposinormality was introduced by Rhaly in a superclass of posinormal operators. In this paper, we give an extension of this notion of supraposinormality to -supraposinormality of operators in the dense norm-attainable class.
