On generalization of midpoint and trapezoid type inequalities involving fractional integrals

Abstract

In this paper, we first prove a lemma for twice differentiable functions . Then we establish some inequalities for mapping whose second derivatives in absolute value are convex via Riemann-Liouville fractional integrals. These results generalize the midpoint and trapezoid inequalities involving Riemann-Liouville fractional integrals given in earlier studies.
