Quasi Efficient Solutions and Duality Results in a Multiobjective Optimization Problem with Mixed Constraints via Tangential Subdifferentials

We take up a nonsmooth multiobjective optimization problem with tangentially convex objective and constraint functions. In employing suitable qualification, we formulate both necessary sufficient optimality conditions for (local) quasi efficient solutions in terms of tangential subdifferentials. Furthermore, under generalized convexity assumptions, state strong, weak converse duality relations Wolfe Mond–Weir types. give number examples to illustrate the new concepts main results this paper.
