Refinements of discrete and integral Jensen inequalities with Jensen’s gap

Author:

Horváth László

Abstract

AbstractMotivated by a paper of Dragomir, we give new refinements for both discrete and integral Jensen inequalities using the Jensen’s gap. As applications, we give refinements of various inequalities verifiable by Jensen’s inequality. Topics covered: norms, quasi-arithmetic means, Hölder’s inequality and f-divergences in information theory.
