摘要
引进了(ψ,Ф,φ)-弱收缩条件和(ψ,Ф,φ^(*))-弱收缩条件的概念,在(具有偏序的)广义度量空间上给出了满足2种收缩条件的2个映射重合的点和公共不动点存在定理.所得结果推广和改进了文献中的一些结果.
The concepts of(ψ,Ф,φ)-weakly contractive condition and(ψ,Ф,φ^(*))-weakly con-tractive condition are introduced,the existence theorems of points of coincidence and common fixed points for two mappings satisfying two contractive conditions on(partially ordered)gener-alized metric spaces are given.The obtained theorems extend and generalize many corresponding results in the literature.
