### A unified common fixed point theorem for a family of mappings

#### Abstract

The main objective of the paper is to prove a unified common fixed point theorem for a family of mappings under a minimal set of sufficient conditions. Our result subsumes and improves a host of common fixed point theorems for contractive type mappings available in the literature of the metric fixed point theory. Simultaneously, we provide some new answers in a general framework to the problem posed by Rhoades (Contemp Math 72, 233-245, 1988) regarding the existence of a contractive definition which is strong enough to generate a fixed point, but which does not force the mapping to be continuous at the fixed point. Concrete examples are also given to illustrate the applicability of our proved result.em for a family of mappings under a minimal set of sufficient conditions.
