New type of G-Mond-Weir type primal-dual model and their duality results with generalized assumptions

Abstract

In this paper, a generalization of convexity, namely Gf-invexity is considered. We formulate a Mond-Weir type symmetric dual for a class of nondifferentiable multiobjective fractional programming problem over cones. Next, we prove appropriate duality results using Gf-invexity assumptions.
