Generalized barycentric coordinates and Jensen type inequalities on convex polytopes
Résumé
In this paper we obtain some direct and converse new multidimensional Jensen’s type inequalities on convex polytopes. Among the inequalities presented, we offer, as a particular case of our general results, a direct and converse multivariate extension of Mercer inequality. The main results are obtained with the aid of the generalized barycentric coordinates. For deriving such inequalities, we will also establish, analyze, and discuss links between barycentric codinates and certain class of partitions of unity. This method also allows us to derive continuous versions of various discrete inequalities established in our recent paper [7].
