With the help of this equality, there are established several fractional Simpson type inequalities for functions whose second derivatives in absolute value are convex. By using special cases of the main results, previously obtained Simpson type inequalities are found for the Riemann-Liouville fractional integral.en10.1515/ms-2023-0049info:eu-repo/semantics/closedAccessSimpson type inequalitiesconvex functionfractional integralstwice differentiable functionIntegral-InequalitiesConvex-FunctionsArticle7336756862-s2.0-85162754679WOS:001183215400009Q2Q2
