我們介紹在完備空間中的弱(Φ,ϕ)收縮函數，並在這類型的收縮下證明其週期點和固定點，我們的結果可推廣或改善最近許多文獻中的固定點定理

We introduce the notion of weaker (Φ,ϕ)-contractive mapping in completemetric spaces and prove the periodic points and fixed points for this type of contraction. Our results generalize or improve many recent fixed point theorems in the literature
