EQUILIBRIUM EXISTENCE FOR MULTI-LEADER-FOLLOWER GENERALIZED CONSTRAINED MULTIOBJECTIVE GAMES IN LOCALLY FC-UNIFORM SPACES

In this article,we introduce and study some new classes of multi-leader-follower generalized constrained multiobjective games in locally FC-uniform spaces where the number of leaders and followers may be finite or infinite and the objective functions of the followers obtain their values in infinite-dimensional spaces.Each leader has a constrained correspondence.By using a collective fixed point theorem in locally FC-uniform spaces due to author,some existence theorems of equilibrium points for the multi-leader-follower generalized constrained multiobjective games are established under nonconvex settings.These results generalize some corresponding results in recent literature.

It is found that generalized geometric programming(GGP) is in fact a special case of generalized convex programming.By selecting a suitable bifunction and calculating its adjoint function,the dual form of the standard GGP problem is derived.Some duality theorems are also obtained with this point of view.The method used is simpler and more general than what appeared in the literature.

This paper discusses the local and global center of the generalized Lienard system, gives two theorems which extend and improve the relative results of [1]-[3].
