摘要
本文在完备度量空间中研究了一种新型映射,对Margherita等人给出的几乎F-压缩映射进行了拓展,定义了一种新型关于g的几乎F-压缩映射,增加了单值映射g,得出了一定条件下,双重映射Tg不动点的存在性问题.
This paper studies a new kind of mapping in a complete metric space and further extends almost type F-Fcontraction proposed by Margherit, et al, and defines a new almost type F-contraction mapping with respect to g, the existence of fixed point of T, g can be assured.
