We obtain necessary and sufficient criteria for optimality in the form of Karush-Kuhn-Tucker conditions. We also introduce a nonsmooth dual problem and provide duality theorems.65-73engInvexityNonsmooth dualityOptimality conditionsVector optimizationArtigo10.1023/A:1021769232224WOS:000083069900003Acesso restrito2-s2.0-0033246201
