%0 Journal Article %T Optimality and Duality in Nonsmooth Multiobjective Optimization Involving V-Type I Invex Functions %A Agarwal RaviP %A Ahmad I %A Husain Z %A Jayswal A %J Journal of Inequalities and Applications %D 2010 %I Springer %X A new class of generalized V-type I invex functions is introduced for nonsmooth multiobjective programming problem. Based upon these generalized invex functions, we establish sufficient optimality conditions for a feasible point to be an efficient or a weakly efficient solution. Weak, strong, and strict converse duality theorems are proved for Mond-Weir type dual program in order to relate the weakly efficient solutions of primal and dual programs. %U http://www.journalofinequalitiesandapplications.com/content/2010/898626
