Generalized L-R-KKM Type Theorems and Applications in L-convex Spaces

FANG Min,DING Xieping (College of Mathematics and Software Science, Sichuan Normal University, Chengdu 610066, Sichuan)  
As a generalization of classical KKM mapping, a new class of generalized LRKKM type mappings is introduced in Lconvex spaces. Some generalized LRKKM type theorems are proved under noncompact setting of Lconvex spaces. As applications, a minimax inequality and a saddle point theorem are established in noncompact Lconvex spaces. These theorems improve and generalize the corresponding results in recent literature.
