Abstract
In this paper we present some relevant properties of Pečarić-type functions and of Mercer-type functions. We discuss both the real case (for convex functions) and the vector case (for delta-convex functions). As a result, we obtain an extension of the Hermite–Hadamard inequality. We also highlight some Schur-convexity properties. A series of recent results in the area are framed in a new vision and extended. In this way, more known proofs are simplified. Appropriate applications complete our study.
