Abstract

In this paper, by using C-class functions, we will present a coupled …xed
problem in b-metric space for the single-valued operators satisfying a generalized
contraction condition. First part of the paper is related to some …xed point theorems,
the second part presents the uniqueness and existence for the solution of the coupled
…xed point problem and in the third part we discuss data dependence, well-posedness,
Ulam-Hyers stability and limit shadowing property of the coupled …xed point set.
