Some inequalities for P-class functions

Functional Analysis 2020-01-22 v1

Abstract

In this paper, we provide some inequalities for PP-class functions and self-adjoint operators on a Hilbert space including an operator version of the Jensen's inequality and the Hermite-Hadamard's type inequality. We improve the H\"{o}lder-MacCarthy inequality by providing an upper bound. Some refinements of the Jensen type inequality for PP-class functions will be of interest.
