Common fixed point theorems for non-self-mappings in metric spaces of hyperbolic type

Abstract

In this paper, the concept of a pair of non-linear contraction type mappings in a metric space of hyperbolic type is introduced and the conditions guaranteeing the existence of a common fixed point for such non-linear contractions are established. Presented results generalize and improve some of the known results. An example is constructed to show that our theorems are genuine generalizations of the main theorems of Assad, Ćirić, Khan et al., Rhoades and Imdad and Kumar. One of the possible applications of our results is also presented.
