Ω-Distance and coupled fixed point in G-metric spaces

Saadati et al. (Math. Comput. Model. 52:797-801, 2010) introduced the concept of Omega-distance in generalized metric spaces and studied some nice fixed point theorems. Very recently, Jleli and Samet (Fixed Point Theory Appl. 2012:210, 2012) showed that some of the fixed point theorems in G-metric spaces can be obtained from quasi-metric space. In this paper, we utilize the concept of Omega-distance in the sense of Saadati et al. to establish some common coupled fixed point results. Also, we introduce an example to support the useability of our results. Note that the method of Jleli and Samet cannot be used in our results.
