向量拟平衡问题的本质解及解集的本质连通区 总被引:9,自引:1,他引:8
本文研究向量拟平衡问题,得到了向量拟平衡问题解的一个存在性结果,证明了在满足一定的连续性和凸性条件的问题构成的空间Y中,大多数(在Baire分类意义下)问题的解集是稳定的,并证明Y的某子集中,每个向量拟平衡问题的解集中至少存在一个本质连通区。作为应用,我们导出了多目标广义对策弱Pareto-Nash平衡点的存在性,证明了在满足一定的连续性和凸性条件的多目标广义对策构成的空间P中,大多数对策的弱Pareto-Nash平衡点是稳定的,并证明了P中的每个对策的弱Pareto-Nash平衡点集中至少有一个本质连通区。 相似文献

In this paper, we study the existence and essential components of the set of weakly Pareto-Nash equilibrium points for multiobjective generalized games in two different uniform topological spaces. We obtain some new existence theorems. Examples show that the results are not identical in two different topological spaces.The author thanks two referees for careful reading of the paper and helpful comments. 相似文献

In this paper, we first give a generalization of Ky Fan's inequality to vector-valued functions. We prove that, for every vector-valued function (satisfying some continuity and convexity conditions), there exists at least one essential component of the set of its Ky Fan's points. As applications, we show that, for every multiobjective game (satisfying some continuity and convexity conditions), there exists at least one essential component of the set of its weakly Pareto-Nash equilibrium points. 相似文献

§1 IntroductionHadamard type well-posedness and Tikhonov type well-posedness are two main typesof concepts of well-posedness. At the beginning of last century,Hadamard firstintroduced the concept of well-posedness in study of optimal problem. Hadamard typewell-posedness of a problem means the continuous dependence of the solution on the dataof such problem. Later,Tikhonov introduced another concept of well-posedness.Tikhonov type well-posedness deals with the behavior ofa prescribed class … 相似文献

In this paper, we introduce and study a class of multi-leader-follower generalized multiobjective games in FC-spaces where the number of leaders and followers may be finite or infinite and the objective functions of leaders and followers get their values in infinite-dimensional spaces. By using a Pareto equilibrium existence theorem of generalized constrained multiobjective games in FC-spaces due to author, some equilibrium existence theorems for the multi-leader-follower generalized multiobjective games are established in noncompact FC-spaces. These results improve and generalize some corresponding results in recent literatures. 相似文献

In this paper, maximal element theorem on Hadamard manifolds is established. First, we prove the existence of solutions for maximal element theorem on Hadamard manifolds. Further, we prove that most of problems in maximal element theorem on Hadamard manifolds (in the sense of Baire category) are essential and that, for any problem in maximal element theorem on Hadamard manifolds, there exists at least one essential component of its solution set. As applications, we study existence and stability of solutions for variational relation problems on Hadamard manifolds, and existence and stability of weakly Pareto-Nash equilibrium points for n-person multi-objective games on Hadamard manifolds. 相似文献

In most of studies on multiobjective noncooperative games, games are represented in normal form and a solution concept of
Pareto equilibrium solutions which is an extension of Nash equilibrium solutions has been focused on. However, for analyzing
economic situations and modeling real world applications, we often see cases where the extensive form representation of games
is more appropriate than the normal form representation. In this paper, in a multiobjective two-person nonzero-sum game in
extensive form, we employ the sequence form of strategy representation to define a nondominated equilibrium solution which
is an extension of a Pareto equilibrium solution, and provide a necessary and sufficient condition that a pair of realization
plans, which are strategies of players in sequence form, is a nondominated equilibrium solution. Using the necessary and sufficient
condition, we formulate a mathematical programming problem yielding nondominated equilibrium solutions. Finally, giving a
numerical example, we demonstrate that nondominated equilibrium solutions can be obtained by solving the formulated mathematical
programming problem. 相似文献

In this paper, we study the system of generalized vector quasi-equilibrium problems which includes as special cases the system of generalized vector equilibrium problems and the system of vector quasi-equilibrium problems, and establish the existence result for its solutions by means of the Kakutani–Fan–Glicksberg fixed points theorem. As special cases, we also derive the existence results for weakly Pareto–Nash equilibrium points for multiobjective generalized game problems and multiobjective game problems. 相似文献

In this paper, the new notions of the generalized Tykhonov well-posedness for multiobjective generalized games are investigated.
By using the gap functions of the multiobjective generalized games, we establish the equivalent relationship between the generalized
Tykhonov well-posedness of the multiobjective generalized games and that of the minimization problems. Some metric characterizations
for the generalized Tykhonov well-posedness of the multiobjective generalized games are also presented. 相似文献
