摘要 作为古典KKM定理的推广,Park在他的工作中介绍了G-凸空间和G-KKM映像.最近,Ding介绍了没有任何凸性结构的有限连续拓扑空间(简称FC-空间)的概念,它包含了C-空间(或H-空间)、G-凸空间、L-凸空间等许多具有抽象凸性结构的拓扑空间作为特例,并证明了FC-空间中的KKM型定理.作为改进和推广,作者在FC-空间中讨论了KKM型定理的一些形式,并获得了FC-空间中Ky Fan型sup inf sup形式不等式和一类极大极小不等式. As generalizations of the KKM theorem, Park introduced the concept of G-convex space and G-KKM mapping in his works. Ding introduced the concept of finitely continuous topological space (in short FC-space) without any convexity assumptions. FC-sapces include C-space (or H-space), G-convex spaces, L-convex spaces and many topological spaces with abstrcat convexity structure as special cases. Consequently, a KKM type theorem in FC-spaces is proved by Ding. In this paper, using the KKM type theorem, the author gives a form of KKM type theorems and obtains sup inf sup inequalities of Ky Fan type and a class of minimax ineoualitv in FC-space.
