考察了满足带有控制项的膨胀条件的两个映射,利用新的方法和思路证明了满足第II及第III膨胀条件的两个映射的重合点和公共不动点的存在定理.所得结果进一步推广和改进了文献中的相应结论.
We consider two mappings satisfying expansive conditions with control- ling items and use new method and idea to prove existence theorems of coincidencepoints and common fixed points for two mappings satisfying II-expansive and III- expansive conditions. The obtained results further generalize and improve the corre- sponding conclusions in references.
