On fixed points of Berinde’s contractive mappings in cone metric spaces

Mujahid AbbasPasquale VetroSafeer Hussain Khan

In this paper we establish some common fixed point theorems for two self-mappings satisfying a generalized contractive condition. This result generalizes well known comparable results in the literature. As an application, a necessary and sufficient condition for a fixed point to be a periodic point for the mapping involved therein, without appealing to continuity, in a cone metric space is established.
