Two selfmaps \(f\) and \(g\) of a metric space \((X,d)\) are said to be noncompatible if there exists some sequence \(\{x_n\}\) such that \(\lim_{n\to \infty} f(x_n)= \lim_{n\to \infty} g(x_n)\) but \(\lim_{n\to \infty} d(f(g(x_n)), g(f(x_n)))\) is either nonzero or nonexistent. In this paper the authors prove two common fixed point theorems for a pair of selfmaps on a metric space without using the full force of noncompatibility and relaxing the Lipschitz type condition.
