Abstract

The purpose of this paper is to introduce the notion of almost generalized (ψ ϕ)-contractive mappings in ordered b-metric spaces by adding four items of d(f2x,fx), d(f2x,y), d(f2x,fy) and d(f2x,x)+d(f2x,fy)2s and establish the fixed point theorem for this kind of mappings. In addition, some examples are provided to illustrate the obtained results.
