几个重合点定理与扩张映射的不动点

Several Coincidence Point Theorems and Fixed Point Theorems for Expansion Mappings

对重合点定理与扩张映射的几个不动点定理得到某些推论,在2—距离空间中扩充了文中某些新的扩张型不动点定理的结果,其主要结果是定理1与定理7.

In this paper, we get some coincidence point theorems and several fixed point theorems for expansion mappings. Furthermore, we extend some results in [7] for some new fixed point theorem of expansion type mappings in 2 - metric space. The main results are theorem 1 and theorem 7.
