Abstract

We consider the generalized minimax programming problem (P) in which functions are locally Lipschitz ( , )-invex. Not only -sufficient but also -necessary optimality conditions are established for problem (P). With -necessary optimality conditions and ( , )-invexity on hand, we construct dual problem (DI) for the primal one (P) and prove duality results between problems (P) and (DI). These results extend several known results to a wider class of programs.
