PY - 2025 TI - Refinement of Jensen-type inequalities: fractional extensions (global and local) JO - AIMS Mathematics SP - 6574 EP - 6588 VL - 10 IS - 3 AB - In this paper, our main objective was to establish new refinements of Jensen's inequality. We focused on the class of convex and harmonic convex functions. In addition, we extended these results to the generalized Caputo-type fractional integral and the generalized local fractional derivative.
