In this article, we introduce a second-order modified contingent cone and a second-order modified contingent epiderivative. We discuss some properties of the second-order cone and the epiderivative, respectively. Moreover, a Fritz John type necessary optimality condition is obtained for the set-valued optimization problems with constraints by using the second-order modified contingent epiderivative and an example is proposed to explain the Fritz John type necessary optimality condition. In particular, we obtain a unified second-order sufficient and necessary optimality condition for the set-valued optimization problems with constraints under twice differentiable L-quasi-convex assumption. 相似文献

In this paper, by virtue of an asymptotic second-order contingent derivative and an asymptotic second-order Φ-contingent cone,
differential properties of a class of set-valued maps are investigated and an explicit expression of their asymptotic second-order
contingent derivatives is established. Then, second-order necessary optimality conditions of solutions are obtained for weak
vector variational inequalities. 相似文献

The concept of a cone subarcwise connected set-valued map is introduced. Several examples are given to illustrate that the cone subarcwise connected set-valued map is a proper generalization of the cone arcwise connected set-valued map, as well as the arcwise connected set is a proper generalization of the convex set, respectively. Then, by virtue of the generalized second-order contingent epiderivative, second-order necessary optimality conditions are established for a point pair to be a local global proper efficient element of set-valued optimization problems. When objective function is cone subarcwise connected, a second-order sufficient optimality condition is also obtained for a point pair to be a global proper efficient element of set-valued optimization problems. 相似文献

In this paper, we introduce the concept of a generalized second-order composed contingent epiderivative for set-valued maps
and discuss its relationship to the generalized second-order contingent epiderivative. We also investigate some of its properties.
Then, by virtue of the generalized second-order composed contingent epiderivative, we establish a unified second-order sufficient
and necessary optimality condition for set-valued optimization problems, which is a generalization of the corresponding results
in the literature. 相似文献

This paper investigates second-order optimality conditions for general multiobjective optimization problems with constraint
set-valued mappings and an arbitrary constraint set in Banach spaces. Without differentiability nor convexity on the data
and with a metric regularity assumption the second-order necessary conditions for weakly efficient solutions are given in
the primal form. Under some additional assumptions and with the help of Robinson -Ursescu open mapping theorem we obtain dual
second-order necessary optimality conditions in terms of Lagrange-Kuhn-Tucker multipliers. Also, the second-order sufficient
conditions are established whenever the decision space is finite dimensional. To this aim, we use the second-order projective
derivatives associated to the second-order projective tangent sets to the graphs introduced by Penot. From the results obtained
in this paper, we deduce and extend, in the special case some known results in scalar optimization and improve substantially
the few results known in vector case. 相似文献
