Coupled fixed point theorems for twisted (α,β)−ψ-expansive mappings

Manoj Kumar, Preeti Bhardwaj


In this paper, we introduce a new concept of cyclic and cyclic ordered α−ψ expansive mappings and investigate the existence of a fixed point for the mappings in this class. Further, we shall derive coupled fixed point theorems in complete metric spaces. The presented theorems generalize and improve many existing results in the literature. Moreover, some examples are given to illustrate our results.
