On refinements of Hermite-Hadamard type inequalities for Riemann-Liouville fractional integral operators

In this paper, we first establish weighted versions of Hermite-Hadamard typeinequalities for Riemann-Liouville fractional integral operators utilizingweighted function. Then we obtain some refinements of these inequalities. Theresults obtained in this study would provide generalization of inequalitiesproved in earlier works.
