Hermite-Hadamard-Fejér Inequalities for Conformable Fractional Integrals via Preinvex Functions

摘要

In this paper, we present a Hermite-Hadamard-Fejér inequality for conformable fractional integrals by using symmetric preinvex functions.We also establish an identity associatedwith the right hand side ofHermite-Hadamard inequality for preinvex functions; then by using this identity and preinvexity of functions and some well-known inequalities, we find several newHermite-Hadamard type inequalities for conformal fractional integrals.
