“…However, this beautiful result was nowhere mentioned in the mathematical literature and was not widely known as Hermite's result (see Pečarić et al [17]). For more recent results which generalize, improve, and extend this classical Hermite-Hadamard inequality, one can see Dragomir [5], Sarikaya et al [19], Xiao et al [27], Bessenyei [4], Tseng et al [24], Niculescu [13], Bai et al [3], Li and Qi [11], Tunç [25], Srivastava et al [23], and references therein. In particular, let us note that Professor Srivastava et al present some interesting refinements and extensions of the Hermite-Hadamard inequalities in n variables (see Theorems 6-12, [23]) and compare with some various inequalities in earlier works.…”
