FC-空间内的KKM型定理及应用
KKM type theorem in FC-space and its applications
-
摘要: 在不具有任何凸性结构和线性结构的有限连续空间(简称FC-空间)巾给出了KKM型定理.并应用此定理,在很弱的条件下证明了鞍点定理和Walras型定理,推广了近期文献中的一些相关的结果.Abstract: In this paper,a KKM type theorem is gained in FC-space without any convexity and linear structure.By applying the theorem,a coincidence theorem and a Walras type theorem are proved under weak assumptions,these theorems generalize some known results in recent literatures.
