We also obtain some new inequalities involving multiplicative integrals by using some properties of preinvex and multiplicatively h-preinvex functions. http://pubs.sciepub.com/tjant/9/3/5/tjant-9-3-5.pdf invex sets preinvex functions multiplicatively h-preinvex functions Multiplicative calculus Hermite-Hadamard inequalities
