摘要
给出λ 超凸度量空间中有限个可交换非扩张映射的公共不动点集及一定条件下任意个可交换非扩张映射的公共不动点集的λ 超凸性(λ<2),并获得一些更一般的不动点定理及一个重要反例。所得结果推广了一些已知的结果。
Showing the λ hyperconvexity of the common fixed points sets of any commuting family of finite nonexpansive maps on λhyperconvex space(λ<2),and of any commuting family of nonexpansive maps on λhyperconvex space(λ<2) under some compactness.Also some more general fixed point theorems and one counterexample are been given.
