摘要
利用广义R-KKM映射,在一般拓扑空间中证明了一个新的重合点定理.作为应用,证明了一个截口定理、一个最佳逼近定理和一个极大极小不等式.
A new coincidence theorem for admissible set-valued mappings is proved in general noncompact topological spaces by using generalized R-KKM mappings. As applications, a section theorem, a best approximation theorem and a minimax inequality are also proved.
