This thesis consists of five chapters. At first, We introduce the study history as well as present situation on KKM theory. Secondly, We discuss the invariability of transfer open valued multimap under the restriction of upper and lower semicontinuity on generalized convex spaces. Then, We obtain new KKM type theorems from the classical KKM theorem by applying upper and lower semicontinuity. We also obtain intersection theorems by applying the KKM type theorems for a multimap from a topological space to another topological space. Further, We obtain Ky-Fan type coincidence theorem by applying known variational results on the KKM type theorems. Finally, We give an application to new theorems.

本文共分五章，首先回顾了KKM理论的研究历史和现状，其次讨论了在一般化凸空间上转移开值映射在上、下半连续映射下的不变性，然后在上、下半连续映射下，以古典的KKM定理为基础得到新的KKM型定理，并利用从一个拓扑空间到另一个拓扑空间的集值映射及KKM型定理得到相交定理，进一步利用已知的KKM型定理的变形结论得到Ky-Fan型重叠定理，最后给出新定理的一个应用。

Bifurcations of Zero Crossings: The isotopy theorem [50], [1] shows that transversal intersections are structur-ally stable, i.e., that "transversal zero-crossings" are structurally stable: their topological properties do not change if the size of the filter is slightly changed.

零相交的叉路：同位定理[50]， [1]表示，横截交叉点结构地是槽枥，即，"横截零相交"结构地是槽枥：他们的拓扑学物产不改变，如果轻微地改变大小过滤器。
