| Abstract: | The saddle point optimality conditions and Lagrangian dual problems of vector optimization for generalized cone subconvex-like mapping in a topological vector space are studied. The optimality conditions of Fritz John's and Kuhn-Tucker's saddle points, and their relations to the efficient solutions and weak efficient solutions are presented. The properties of solutions are characterized with the Lagrangian dual problems and scalarization of vector optimization problems. The dual theorems on vector optimization problems, in which the objective mapping is generalized cone subconvex-like, and in which the constraint mapping satisfies generalized Slater constraint qualifications, are given. |
