A Reduction Theorem for Inequalities Involving Convex Functions and Its Applications
摘要
In this paper we obtain a general method that allows to prove inequalities for convex functions. In fact, we show that proving an inequality for every convex function is equivalent to proving that inequality for a small class of simple convex functions. Also, we show the power of this tool by proving several results: Jensen’s inequality, an integral version of the Petrović’s inequality, two new integral Karamata’s inequality, and a new version of Hermite-Hadamard inequality with general measures.
