Fractional Hermite–Hadamard type inequalities for interval-valued functions

Abstract

Abstract We introduce the concept of interval harmonically convex functions. By using two different classes of convexity, we get some further refinements for interval fractional Hermite–Hadamard type inequalities. Also, some examples are presented.
