在完备G-度量空间的框架下,利用弱相容映象的概念,讨论了4个自映象的公共不动点的存在性和唯一性问题,证明了一个新的公共不动点定理.所得结果改进和推广了本领域的相关结果.
Using the concept of weakly compatible mapping, the paper discussed the existence and uniqueness of the common fixed point for four self-mappings in complete G-metric space, and proved a new common fixed theorem. The results have improved and extended the corresponding results of this field.
