 Abstract
To study the operator inequalities, the notions of class A operators and quasi-class A operators are developed up to recently. In this paper, quasi- class operator for and is introduced as a new notion, which generalizes the quasi-class A operator. We obtain some structural properties of these operators. Also we characterize quasi- classes for n and via backward extension of weighted shift operators. Finally, we give a simple example of quasi- operators with two variables.
