New Inequalities for Hermite-Hadamard and Simpson Type and Applications
  In this paper, we obtain new bounds for the inequalities of Simpson and Hermite-Hadamard type for functions whose second derivatives absolute values are P-convex. These bounds can be much better than some obtained bounds. Some applications for special means of real numbers are also given.
