本篇論文主要是探討在完備的偏序度量空間中，一個建立在 φ,ϕ,ξ：R^+→R^+ 和 ψ：R^(+^4 )→R^+ 四個函數上的循環弱收縮函數之固定點定理。

The purpose of this paper is to study a fixed point theorem for a mapping satisfying the cyclical generalized contractive conditions based on four functions φ,ϕ,ξ：R^+→R^+ and ψ：R^(+^4 )→R^+ in complete partial metric spaces.Our results generalize and improve many recent fixed point theorems in the literature.
