利用度量空间中自映象对相容和次相容的条件,讨论了完备度量空间中一类Ф-压缩条件下4个映象的公共不动点的存在性与唯一性,得到一个新的公共不动点定理,扩展了原有的结果.
By using the compatible and subcompatible conditions of self-mapping pairs in metric spaces, the paper discussed the existence and uniqueness of a common fixed point theorem for four self-mappings with Ф-contractive mapping condition in complete metric spaces and obtained a new common fixed theorem which extended some previous results.
