ε‐Properly Efficiency of Multiobjective Semidefinite Programming with Set‐Valued Functions

open access: yesMathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017
In this paper, we study the ε‐properly efficiency of multiobjective semidefinite programming with set‐valued functions. Firstly, we obtain the scalarization theorems under the condition of the generalized cone‐subconvexlikeness. Then, we establish the alternative theorem which contains matrixes and vectors, the ε‐Lagrange multiplier theorems, and the ε‐

A Characterization of E‐Benson Proper Efficiency via Nonlinear Scalarization in Vector Optimization

open access: yesJournal of Applied Mathematics, Volume 2014, Issue 1, 2014., 2014
A class of vector optimization problems is considered and a characterization of E‐Benson proper efficiency is obtained by using a nonlinear scalarization function proposed by Göpfert et al. Some examples are given to illustrate the main results.

The Relationship between Two Kinds of Generalized Convex Set‐Valued Maps in Real Ordered Linear Spaces

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
A new notion of the ic‐cone convexlike set‐valued map characterized by the algebraic interior and the vector closure is introduced in real ordered linear spaces. The relationship between the ic‐cone convexlike set‐valued map and the nearly cone subconvexlike set‐valued map is established.

ϵ‐Henig Saddle Points and Duality of Set‐Valued Optimization Problems in Real Linear Spaces

open access: yesThe Scientific World Journal, Volume 2013, Issue 1, 2013., 2013
We study ϵ‐Henig saddle points and duality of set‐valued optimization problems in the setting of real linear spaces. Firstly, an equivalent characterization of ϵ‐Henig saddle point of the Lagrangian set‐valued map is obtained. Secondly, under the assumption of the generalized cone subconvexlikeness of set‐valued maps, the relationship between the ϵ ...

Strict Efficiency in Vector Optimization with Nearly Convexlike Set‐Valued Maps

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
The concept of the well posedness for a special scalar problem is linked with strictly efficient solutions of vector optimization problem involving nearly convexlike set‐valued maps. Two scalarization theorems and two Lagrange multiplier theorems for strict efficiency in vector optimization involving nearly convexlike set‐valued maps are established. A

A Generalized Alternative Theorem of Partial and Generalized Cone Subconvexlike Set‐Valued Maps and Its Applications in Linear Spaces

open access: yesJournal of Applied Mathematics, Volume 2012, Issue 1, 2012., 2012
We first introduce a new notion of the partial and generalized cone subconvexlike set‐valued map and give an equivalent characterization of the partial and generalized cone subconvexlike set‐valued map in linear spaces. Secondly, a generalized alternative theorem of the partial and generalized cone subconvexlike set‐valued map was presented.
