摘要
本文讨论凸度量空间中集值映象的重合点和不动点的存在性以及乘积空间中非扩张映象的不动点性质。本文所得结果推广和发展了文献[1—3]中的一些重要结果。
In this paper,the existence of coincidence point and fixed point for set- valued mappings in convex metric spaces and the property for nonexpansive mappings in product spaces are discussed.The results presented in this paper generalize and devecop some important results in[1-3].
