摘要 给出了2类新的非扩展映象,并对其性质进行了研究.利用这些性质,得到了非扩展映象一些不动点定理,推广、改进了前人的一些重要结果. Two new nonexpansive mappings are introduced and the characters of the nonexpansive mappings are studied.Some fixed point existence theorems are given by these characters,some important results of the paper are improved and developed.
