摘要
在2-距离空间中,引入了(Ag)型R-弱交换映象的概念.利用自映象对的非相容性和(Ag)型R-弱交换条件,建立了一类具有平方型的φ-压缩条件,并在此基础上证明了4个映象的公共不动点的存在性和唯一性,得到了一个新的公共不动点定理.
In 2-metric spaces,the concept of(Ag) type R-weak commutative mapping is introduced.By using the noncompatible and(Ag) type R-weak commutative conditions of self-mapping pairs in 2-metric spaces,a class of twice power type φ-contractive condition is established and the existence and uniqueness of the common fixed point for four self-mappings on given conditions are discussed,a new common fixed theorems is obtained.
