广义凸空间上重合点定理和极大极小不等式
Coincidence Point Theorems and Minimax Inequalities on Generalized Convex Spaces
【摘要】 利用已知的KKM型定理,在广义空间上得到若干个新的重合点定理和推广的Fan-Browder型不动点定理,并且讨论了Von Newmann-Sion型极大极小不等式.主要结果改进和推广了文献中的相应结论.
【Abstract】 By using well-known KKM type theorems,some new Ky Fan type coincidence theorems and generalized Fan-Browder type fixed point theorems on generalized convex spaces were obtained,and then Von Neumann-Sion type minimax inequlaties were discussed. The main results improve and generalize the corresponding results in the recent literature.
