在局部凸拓扑线性空间中的弱肾集上得到了一个非扩张映射对的公共不动点定理和一个最佳逼近定理,改进了Hussain和Khan的相应结论.所得结果是许多已有结论的推广.
On weakly compact sets in locally convex linear topological space, a common fixed - point theorem and a best approximation theorem of a pair of nonexpansive mappings are obtained. This extends results of Hussain and Khan and unifies many well -known conclusions of others.
