Summary
Abstract In the paper, the authors establish some new inequalities of Hermite-Hadamard type for functions whose third derivatives are convex. Introduction It is common knowledge in mathematical analysis that a function f : I ⊆ R → R is said to be convex on an interval I if the inequality f λx + ( – λ)y ≤ λf (x) + ( – λ)f (y) is valid for all x, y ∈ I and λ ∈ [ , ]. If f : I ⊆ R → R is a convex function on I and a, b ∈ I with a < b, the double inequality f a + b ≤ b f (x) dx ≤ f (a) + f (b) holds.
