Hermite-Hadamard Type Integral Inequalities for Functions Whose Mixed Partial Derivatives Are Co-ordinated Preinvex

Abstract

The main objective of this article is to establish integral identity relating the left side of Hermite- Hadamard type inequality. By using this identity, we establish some new Hermite-Hadamard type integral inequalities for functions whose mixed partial derivatives are co-ordinated preinvex. These consequences generalize numerous outcomes established in previous studies for these classes of functions.
