Duality for a nondifferentiablemultiobjective fractional programming problem using Gf -invexity

Abstract

In this paper, a generalization of convexity, namely Gf -invexity is considered. We formulate a pair of Mond-Weir and Wolfe -type symmetric duals for a class of nondierentiable multiobjective fractional programming problems over arbitrary cones. Next, we demonstrate suitable duality comes about utilizing Gf -invexity assumptions.
