Abstract:

We introduce a new Fenchel dual problem in vector optimization inspired by the form of the Fenchel dual of the scalarized primal multiobjective problem. For the vector primal and dual problems we prove weak and strong duality. Furthermore, we recall two other Fenchel-type dual problems introduced in the past in the literature, in the vector case, and make a comparison among all three duals. Moreover, we show that their sets of maximal elements are equal.
