Abstract

A generalized lemmas is proved and several new inequalities for differentiable co-ordinated convex and concave functions in two variables are obtained.

Highlights

  • This remarkable result is well known in the literature as the Hermite-Hadamard inequality for convex mapping

  • Some refinements of the Hermite-Hadamard inequality on convex functions have been extensively investigated by a number of authors (e.g., [1,2,3,4])

  • A modification for convex functions which is known as coordinated convex functions was introduced as follows by Dragomir in [5]

Summary

Introduction

A generalized lemmas is proved and several new inequalities for differentiable co-ordinated convex and concave functions in two variables are obtained. Let f : I ⊆ R → R be a convex function and a, b ∈ I with a < b; we have the following double inequality: f(a This remarkable result is well known in the literature as the Hermite-Hadamard inequality for convex mapping.
