Coupled fixed points for mappings on a $b$metric space with a graphA. K. MirmostafaeeDepartment of Pure Mathematics, Center of Excellence in Analysis on Algebraic Structures, Ferdowsi University of Mashhad, Iran Email: mirmostafaei@ferdowsi.um.ac.irAbstract: In this paper, we will develop a new method to study coupled fixed points of a mapping $T:X\times X\to X$, where $(X,d)$ is a special class of $b$metric spaces endowed with a graph. We will prove some general fixed point theorems which enable us to extend some old results in fixed point theory. Moreover, we will extend Edelstein’s fixed point theorem for two variable mappings in $\epsilon $chainable $b$metric spaces. Keywords: Coupled fixed point; connected graph; Picard operator; $b$metric space. Classification (MSC2000): 47H10; 54M15, 54C10 Full text of the article: (for faster download, first choose a mirror)
