Operator Popoviciu's inequality for superquadratic and convex functions of selfadjoint operators in Hilbert spaces

Abstract

In this work, operator version of Popoviciu's inequality for positive selfadjoint operators in Hilbert spaces under positive linear maps for superquadratic functions is proved. Analogously, using the same technique operator version of Popoviciu's inequality for convex functions is obtained. Some other related inequalities are also deduced.
