Wikipedia says that Jensen’s inequality is a special case of Karamata’s inequality . Hence, if a function satisfies Karamata’s inequality, it satisfies. PDF | Three classical general inequalities—those of Karamata, Schur and Muirhead—are proved in this article. They can be used in proving other inequali- ties. jorization inequality where the majorization condition is replaced by a more The inequality presented in the article is a consequence of Karamata’s majoriza-.

convex analysis – Convexity defined by Karamata inequality – Mathematics Stack Exchange

Just as the Jensen karmaata is used to define convex functions, can the Karamata inequality be used instead to define convex functions? We may assume that the numbers are in decreasing order as specified in 2. This is false by some stupid reasons. It generalizes the discrete form of Jensen’s inequality. Let I be an interval of the real line and let f denote a real-valued, convex function defined on I.
