摘要
最近,Wu和Yuan将Brouwer-Schauder-Tychonoff不动点定理推广到H-空间.本文首先建立一个逼近选择定理,然后使用这个结果建立一个新的不动点定理,很大地改进和推广了Wu和Yuan的结果.
Recently, Wu and Yuan in [1] extended Brouwer-Schauder-Tychonoff fixed point theorem to H- Spaces. The purpose of this paper is to establish a new fixed point theorem which improves on and generalizes Wu and Yuan's result in [1], by using a new approximation selection theorem for upper semicontinuous multivalued mappings.
