Remarks on Some Recent Coupled Coincidence Point Results in Symmetric G-Metric Spaces

الملخص EN

We use a method of reducing coupled coincidence point results in (ordered) symmetric G-metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

Our results generalize, extend, unify, and complement recent coupled coincidence point theorems in this frame, established by Cho et al.

(2012), Aydi et al.

(2011), and Choudhury and Maity (2011).

Also, by using our method several recent tripled coincidence point results in ordered symmetric G-metric spaces can be reduced to the coincidence point results with one variable.
