The property of GMS-KKM mappings and the application to the variational inequality
【摘要】 引入了超S-γ-广义拟凸(凹)函数,建立了广义度量S-KKM映射与超S-γ-广义拟凸(凹)函数的关系.作为应用,获得了超凸度量空间中的新的KyFan极大极小不等式和鞍点定理.
【Abstract】 In this paper,the hyper S-γ-generalized quasi-convex(resp.,concave) functional is introduced,the relation between the generalized metric S-KKM mapping and the hyper S-γ-generalized quasi-convex(resp.,concave) functional is established. As application,the new Ky Fan minimax inequality and the existence theorem for saddle points are obtained in hyperconvex metric spaces.
