摘要
在完备的2-距离空间中,研究了一类涉及四个映象的带有对称函数的满足一定压缩型条件的公共不动点的存在性问题.利用广义弱交换映象概念,证明了这类带有对称函数的压缩映象的新型公共不动点定理,将相关文献中的结果扩展到了2-距离空间中.
The existence problem of common fixed point for a class of contractive type condition involving four mappings with symmetric function in complete 2-metric spaces was studied. A new common fixed point theorem for this class of contractive type mappings with symmetric function was proved by using generalized-quasi-weak commutativity. The results obtained in this paper extend the corresponding results in some references to 2- metric spaces.
