我們考慮在完備距離空間上有上界且上半連續的函數，並嘗試建立一些集合值函數的性質，進而運用這些性質來証明集合值函數的定點定理。

We consider the bounded above and upper semicontinuous functions on complete metric spaces. We establish some results about set-valued mapping, and apply them to established some fixed points of set-valued mapping, which are generalizations of those in Caristi [2].
