Nondifferentiable multiobjective symmetric duality with FF-convexity over cones

In the present paper, a pair of Wolfe type nondifferentiable multiobjective second-order symmetric dual programs over arbitrary cones are formulated. Using the concept of weak efficiency with respect to a convex cone, weak, strong and converse duality theorems are studied under second-order KK–FF-convexity assumptions. Self-duality is also discussed.
