摘要
利用一致凸度量空间中的凸性模和自映象对的次相容性,讨论了一类4个自映象的公共不动点的存在性和唯一性问题,得到了一个公共不动点定理.该结果改进和推广了近期的相关结果.
Using the sub‐compatibility of convex modulus and self‐mapping pair in uniformly convex metric spaces ,we discuss the existence and uniqueness of some common fixed points with four self‐mappings in this paper .A new common fixed point theorem is obtained ,which largely improves and extends some re‐lated results that have been published recently in uniformly convex metric spaces .
