Triple Fixed Point Theorems for Weak (ψ-Φ)

Abstract

The notion of coupled fixed point is introduced in by Bhaskar and Lakshmikantham in [2]. Very recently, the concept of the tripled fixed point is introduced by Berinde and Borcut [1]. They also proved some triple fixed point theorems. In this manuscript, by using the weak (ψ-φ)-contraction, the results of Berinde and Borcut [1] are generalized. © 2013 EUDOXUS PRESS, LLC.
