Abstract
In this paper, we introduce a class of operators on a Hilbert space namely quasiposinormal operators that contain properly the classes of normal operator, hyponormal operators, M–hyponormal operators, dominant operators and posinormal operators . We study some basic properties of these operators .Also we are looking at the relationship between invertibility operator and quasi-posinormal operator
Keywords
posinormal operators , Hyponormal operators , M , hyponormal operators , dominant operators
