Higher order duality in multiobjective fractional programming with support functions

In this paper a new class of higher order (F ,ρ,σ)-type I functions for a multiobjective programming problem is introduced, which subsumes several known studied classes. Higher order Mond–Weir and Schaible type dual programs are formulated for a nondifferentiable multiobjective fractional programming problem where the objective functions and the constraints contain support functions of compact convex sets in Rn. Weak and strong duality results are studied in both the cases assuming the involved functions to be higher order (F ,ρ,σ)-type I. A number of previously studied problems appear as special cases
