摘要 Caristi-Kirk在文献[9]中,对于度量空间上的非线性映射给出了一个非常重要而且十分有趣的不动点定理.这个结果已被应用到研究内向映射理论和正规可解性理论之中.Kasahara在文献[7]中,又把这个定理推广成映射族的公共不动点定理.本文又给出了这个定理的一个新的推广.我们的结果包含了上述作者的某些结果. The important fixed point theorem for nonlinear mappings in metric spaces is given by Caristi and Kirk[9]. Kasahara[7] extend this theorem to a common fixed point theorem on collections of mappings. In this paper, we give a new extension of Caristi-Kirk's theorem. Our results contain some results of above and other authors.
