Abstract
In the paper, new Fritz John type necessary optimality conditions and new
Karush-Kuhn-Tucker type necessary opimality conditions are established for
the considered nondifferentiable multiobjective programming problem involving
locally Lipschitz functions. Proofs of them avoid the alternative theorem
usually applied in such a case. The sufficiency of the introduced
Karush-Kuhn-Tucker type necessary optimality conditions are proved under
assumptions that the functions constituting the considered nondifferentiable
multiobjective programming problem are G-V-invex with respect to the same
function ?. Further, the so-called nondifferentiable vector G-Mond-Weir dual
problem is defined for the considered nonsmooth multiobjective programming
problem. Under nondifferentiable G-V-invexity hypotheses, several duality
results are established between the primal vector optimization problem and
its G-dual problem in the sense of Mond-Weir.
