Duality for nondifferentiable static multiobjective variational problems involving generalized (F,rho)-convex functions

Using the generalized Schwarz inequality, we establish some weak duality theorems for nondifferentiable static multiobjective variational problems involving generalized (F, rho)-convex functions. Later in the sequel, we introduce three dual models for the nondifferentiable static multiobjective fractional variational problems and derive weak duality results for such programs.
