摘要: 通过在[1,∞)3上引入两种实函数类Σ和Γ, 在乘积度量空间上给出满足σ(γ)-压缩条件映射的唯一不动点存在性定理, 并给出乘积度量空间上的Banach型不动点定理、 Kannan型不动点定理、 Chatterjea型不动点定理和Ciric型不动点定理及其推广的不动点定理.

关键词: 乘积度量空间, 不动点, 函数类Σ; 函数类Γ

Abstract: By introducing two real function classes Σ and Γ on [1,∞)3, the author gave the existence theorems of unique fixed points for mappings with σ(γ)-contractive conditions on multiplicative metric spaces, and gave Banach type fixed point theorem, Kannan type fixed point theorem, Chatterjea type fixed point theorem and Ciric type fixed point theorem and their generalized fixed point theorems on multiplicative metric spaces.

Key words: multiplicative metric space, fixed point, function class Σ, function class Γ
