摘要
引入广义L-KKM映射的概念,它包含R-KKM映射,G-KKM映射,H-KKM映射为其特例.在具有(H)性质的拓扑空间中证明了一些新的广义L-KKM型定理,并进一步获得了关于开覆盖的匹配定理.作为广义L-KKM型定理应用,证明了非空交定理.
The concept of generalized L-KKM mapping is introduced. Generalized L-KKM mapping includes R-KKM mapping, G-KKM mapping, H-KKM mapping as special cases. Some new generalized L-KKM type theorems are proves in a topological space with property (H), furthermore, matching theorems with open cover are obtained. As application of generalized L-KKM type theorems, a nonempty intersection theorem is proved.
