在本論文中,我們首先定義弱美爾基勒型函數,再利用這定義和相容性質,我們證明在完備度量空間中,兩個單值函數和兩個多值函數,在弱美爾基勒收縮條件下的一些公共固定點定理

In this paper, we first define a weaker Meier-Keeler type function . Next, we establish some common fixed point theorems for two single-valued functions and two set-valued functions satisfying the weaker Meier-Keeler contractive conditions in a complete metric space using the concept of compatibility.
