摘要
引进了3个实函数类Φ,Ψ及L并考虑了3个满足压缩型条件的映射族,利用W-空间上的映射族的反交换性或具有交换点条件得到了若干个映射族具有唯一公共不动点的定理,同时给出了它们的特殊结果,所得结果推广和改进了很多相应结论,
Three classes Ф, ψ and L of real functions are introduced and three mappings satisfying some contractive conditions are considered. By using the converse commuting property of mappings or the condition that mappings have a commuting point on W-spaces, several unique common fixed point theorems are obtained and their particular conclusions are also given. The obtained results generalize and improve some existing conclusions.
