“…The inequality (1.1) may be considered as a necessary and sufficient condition for a function to be convex. For useful details on integral inequalities of Hermite-Hadamard type, see [1,2,5,6,7,11,12,13,14,16,17,18,19,21,22] and closely related references therein. In recent years, some extensions and generalizations have been considered for the classical convexity using novel and innovative techniques, see [1,3,4,7,8,9,10,11,12,13,14,15,16,17,18,21,22] and closely related references therein.…”
