Fixed and related fixed point theorems for three maps in G-metric spaces

摘要

Using the setting of G-metric spaces, unique common fixed points of three maps that satisfy a generalized(φ, Ψ)-weak contractive condition are obtained. It is noted that the existence of a fixed point of any one of the mappings implies that the three mappings have a common fixed point. These results extend and generalize various well known comparable results in the existing literature.
