ON P-HYPONORMAL COMPOSITION OPERATORS

Abstract

Summary: In this paper, we introduce P-hyponormal composition operators on \(L^2\)-spaces and study some of their properties. We show that Fuglede-Putnam's (briefly FP) theorem holds for P-hyponormal and P-hyponormal composition operators.

Keywords

\(P\)-hyponormal operators, composition operators, Linear composition operators, \(L^2\)-spaces, Subnormal operators, hyponormal operators, etc.
