Fractional Hermitea??Hadamard inequalitie s for ( s,m)$( s,m)$-convex or s-concave function s

摘要

In this article, fractional integral is considered. Some new upper bounds of the distance between the middle and left of Hermitea??Hadamard type inequalities for fractional integrals are established for ((s,m))-convex or s-concave functions.
