Common fixed point of two \(R\)-weakly commuting mappings in \(b\)-metric spaces (Q492526)

In this paper, a common fixed point theorem for two mappings defined in \(b\)-metric space, satisfying some extension of contraction condition, is proved. One important assumption is that the mappings are ``weakly commuting''. The \(b\)-metric (in Czerwik's sense) means the ball-metric. Reviewer's remark. We note that Example 13 presented in the paper is not too interesting, so it would be useful to give a better one ``to support Theorem 12''.
