Hermite-Hadamard-Fejér type inequalities for p-convex functions

In this paper, firstly, Hermite-Hadamard-Fejér type inequalities for p-convex functions are built. Secondly, an integral identity and some Hermite-Hadamard-Fejér type integral inequalities for p-convex functions are obtained. Finally, some Hermite-Hadamard and Hermite-Hadamard-Fejér inequalities for convex, harmonically convex and p-convex functions are given. Some results presented here for p-convex functions provide extensions of others given in earlier works for convex and harmonically convex and p-convex functions.
