在2-距离空间的框架下,利用映象对的甜一相容性条件,建立了一类新的平方型压缩条件,讨论了此类映象耦合公共不动点的存在性和唯一性.证明了一个新的耦合公共不动点定理.也提供了一个有效的例子来支持该文的新结果.该文的结果改善了之前文献中的相关结果.
In the framework of 2-metric spaces, a new class of square contractive conditions were established and the existence and uniqueness of the coupled common fixed point in given conditions were discussed, by means of the w-compatible condition for the pair of mappings. Then a new coupled common fixed point theorem was proved. Several illustrative examples were also given in support of the new theorem. The work improves the relative results in the recent literatures.
