Refinements of some fractional integral inequalities for refined (α, h− m) -convex function

This article investigates new inequalities for generalized Riemann–Liouville fractional integrals via the refined (α, h− m) -convex function. The established results give refinements of fractional integral inequalities for (h− m) -convex, (α, m) -convex, (s, m) -convex, and related functions. Also, the k-fractional versions of given inequalities by using a parameter substitution are provided. © 2021, The Author(s).
