Inequalities involving multivariate convex functions. II. (English) Zbl 0699.26009

Continuing the work of the author and of J. E. Pečarić [J. Math. Anal. Appl. 137, No.2, 541-549 (1989; Zbl 0672.26010)], this paper gives some inequalities for multivariate convex functions. Among them: a refinement of Jensen’s inequality and an extension of Fejér’s inequality [see D. S. Mitrinović and I. B. Lacković, Aequationes Math. 28, 229-232 (1985; Zbl 0572.26004)]. They are obtained with the aid of generalized simplex splines.
