In this paper a concept of contractible closed set is introduced in H-spaceand a generalized KKM theorem (Theorem 1)which is parallel with C-KKM theorem isobtained.
在H-空间中引入了可缩闭集的概念，得到了一个与C-KKM定理相平行的广义KKM定理。
In the second chapter, by using generalized R-KKM mappings, we obtain a new coincidence theorem for admissible set-valued mappings in topological Spaces without any convexity structure.
