“…Considering the Simpson type inequalities, many researches generalized and extended them. For example, Hsu et al [1], Du et al [2], Noor et al [3], İşcan et al [4] and Tunç et al [5] obtained some Simpson type inequalities for differentiable mappings which are convex, extended (s, m)-convex, geometrically relative convex, p-quasi-convex mappings and h-convex, respectively. Further results involving the Simpson type inequality in question with applications to Riemann-Liouville fractional integrals have been explored out by some scholars, including Set et al [6] and Hwang et al [7] in the study of the Simpson type inequalities using convexity, as well as İşcan [8] in the study of the Simpson type inequalities using s-convexity.…”
