Abstract
In this chapter, we introduce the class of eta(phi)-convex functions which is larger than the class of.-convex functions introduced by Gordji et al. (Preprint Rgmia Res Rep Coll 1-14, 2015 [1]). Some Fejer type integral inequalities are established for this new class of functions. As consequences, we deduce some Hermite-Hadamard type inequalities involving different kinds of fractional integrals.
