Coupled fixed point results for rational type contractions involving generalized altering distance function in metric spaces

In this paper, we study some unique coupled coincidence points for rational type contractions involving generalized altering distance functions in metric spaces. Our results unify and generalize various known comparable results from the current literature, Gupta et. al. \cite{VRNA}, Nashine and Aydi \cite{HKH}, Rashwan and Saleh \cite{RS} and many known results. An example is also given to support our main results.
