Namely, the generalizations of the midpoint type inequalities in the case of differentiable co-ordinated (s_1," " s_2)-convex functions in the second sense on the rectangle from the plain are established. In addition to this, it is presented several inequalities to the case of Riemann-Liouville fractional integrals and k-Riemann-Liouville fractional integrals by choosing the special cases of our obtained main results.en10.17776/csj.1088703info:eu-repo/semantics/openAccessMidpoint inequalityCo-ordinated (s_1" " s_2)-convex functionGeneralized fractional integrals.Article4334774911131907
