A Study on Quasi Class Q Operator


Dr. S.K.Latha
Abstract

In this paper quasi class operator is introduced with example and compared with normaloid operator. Necessary and sufficient condition for a composition operator to be quasi class is given with an example. Also weighted composition operator and generalized Aluthge transform are characterized to be of quasi class .

Keywords
Class operators, composition Operators.
