利用古典的KKM原理的开[闭]形式得到FC-空间上的KKM型定理并给出局部FC-空间上的上[下]半连续映射的几乎不动点定理,最后给出在局部FC-空间上具有闭值且其值为FC-子空间的上半连续映射的不动点定理.
We use the well known open [closed] version of classical KKM principle to obtain KKM type theorem on FC-spaces and then obtain several almost fixed point theorems for upper [ resp. lower] semicontinuous muhimap in locally FC-spaces, and then give some fixed point theorems for upper semicontinuous muhimap with closed values which is a FC-subspace on locally FC-spaces.
