      다국어 초록 (Multilingual Abstract)

      ?-Saddle point theorems and e-duality theorems for several kinds of optimization problems have been studied ([3],[4],[5],[6],[7],[8]). Using Ekeland Variational Principle ([2]), Liu ([6]) formulated a Wolfe type dual problem for points near to ?-approximate solutions of a nonconvex multiobjective optimization problem, and then proved duality theorems which hold between the primal problem and the dual problem. Very recently, Dinh et al ([1]) established sequential saddle point theorems for exact solutions of convex optimization problems which hold without any constraint qualification.
      In this talk, we presented ?-saddle point theorems and ?-duality theorems for ?-approximate solutions of convex optimization problems are investigated. We give a sequential e-saddle point theorem for an ?-approxirnate solution of a convex optimization problem which holds without any constraint qualification, and then present an ?-saddle point theorem for an ?-approximate solution which holds under a weaken constraint qualification. Furthermore we formulate a Wolfe type dual problem for ?-approximate solutions for a convex optimization problem, and then using the ?-saddle point theorem, we establish duality theorems which hold between the primal problem and the dual problem.
