“…In recent years, the Hermite-Hadamard integral inequality has been the subject of very active research. Various improvements, generalizations, and variants of this inequality can be found in the papers [1,3,8,9,11,12,14,16,20,23,24,27,28,32] and closely related references therein. In [15], the late Pachpatte established some Hadamard-type inequalities for the product of two convex functions.…”
