Some novel fractional inequalities related to the left and right sides of the Hermite-Hadamard-Mercer inequalities are established for differentiable mappings whose absolute values of the derivatives are h-convex. Moreover, we construct new inequalities for these differentiable functions using Holder's inequality.en10.2298/FIL2606991Ainfo:eu-repo/semantics/closedAccess[Keyword Not Available]Article406199120102-s2.0-105034051753WOS:001718786600001Q2Q20000-0001-8843-955X
