Coupled fixed point results for (varphi,G)-contractions of type (b) in b-metric spaces endowed with a graph
The purpose of this paper is to present some existence results for coupled fixed points of generalized contraction type operators in b-metric spaces endowed with a directed graph.Our results generalize the results obtained by Gnana Bhaskar and Lakshmikantham in [T.Gnana Bhaskar, V. Lakshmikantham, Nonlinear Anal., 65 (2006), 1379-1393].Data dependence, well-posednes …
