Coincidence Points and Common Fixed Points for Expansive Type Mappings in b-Metric Spaces

The main purpose of this paper is to obtain sufficient conditions for existence of points of coincidence and common fixed points for a pair of self mappings satisfying some expansive type conditions in b-metric spaces. Finally, we investigate that the equivalence of one of these results in the context of cone b-metric spaces cannot be obtained by the techniques using scalarization function. Our results extend and generalize several well known comparable results in the existing literature.
