FG- coupled fixed point theorems for various contractions in partially ordered metric spaces
摘要:
本文在半序完全度量空间中引入FG-耦合不动点,它是非线性映射耦合不动点的推广。讨论了不同压缩映射的FG耦合不动点的存在唯一性定理.我们的定理推广了Gnana Bhaskar和Lakshmikantham [T. Gnana Bhaskar,V. Lakshmikantham;半序度量空间中的不动点定理及其应用;非线性分析65(2006)1379 - 1393]。
英文摘要:
In this paper we introduce FG- coupled fixed point, which is a generalization of coupled fixed point for nonlinear mappings in partially ordered complete metric spaces. We discuss existence and uniqueness theorems of FG- coupled fixed points for different contractive mappings. Our theorems generalizes the results of Gnana Bhaskar and Lakshmikantham [T. Gnana Bhaskar, V. Lakshmikantham; Fixed point theorems in partially ordered metric spaces and applications; Nonlinear Analysis 65 (2006) 1379 -1393].
