The Maximal Element Theorem in Noncompact Hyperconvex Metric Spaces and Its Application to the Minimax Question and the Saddle Point Question

WEN Kai-ting Department of Mathematics, Bijie University, Bijie 551700, China  
An existence theorem for maximal elements is established in noncompact sub-admissible subsets of noncompact hyperconvex metric spaces. As applications, a Browder-Fan fixed point theorem, a Ky Fan minimax inequality and an existence theorem for saddle points are obtained.
