Second-Order Duality for Nondifferentiable Multiobjective Programming Involving (φ, ρ)-Univexity

The concepts of (&phi, ρ)-invexity have been introduced by Carsiti, Ferrara and Stefanescu. We consider a second-order dual model associated to a multiobjective programming problem involving support functions and a weak duality result is established under appropriate second-order (&phi, ρ)-univexity conditions.
