Common fixed point of four maps in b-metric spaces

Abstract

In this paper, some common fixed point results for four mappings satisfying generalized contractive condition in a b-metric space are proved.Advantage of our work in comparison with studies done in the contextof b-metric is that, the b-metric function used in the theorems andresults are not necessarily continuous. So, our results extend and improve several comparable results obtained previously. We also presenttwo examples that show the applicability and validity of our results.
