Gadhi, N. Optimality conditions and duality theorems for non-Lipschitz optimization problems. (English) Zbl 1070.90096 Port. Math. (N.S.) 61, No. 3, 317-327 (2004). Summary: We are concerned with a multiobjective optimization problem (P). Using a notion of approximation derived from A. Jourani and L. Thibault [Math. Oper. Res. 18, No. 2, 390–401 (1993; Zbl 0779.49021)] we give necessary and sufficient optimality conditions for (P). We establishe also duality theorems.
