Coupled and tripled coincidence point results without compatibility [PDF]
Fixed Point Theory and Applications, 2012 Abstract In this article, we introduce a new and simple approach to coupled and tripled coincidence point theory. By using our method, we establish coupled coincidence point results of Lakshmikantham and Ćirić, Binayak et al., Alotaibi and Alsulami without any type of commutativity condition on F and g.

Coupled coincidence point theorems in (intuitionistic) fuzzy normed spaces [PDF]
Journal of Inequalities and Applications, 2013 Abstract In this paper, we prove some coupled coincidence point theorems in fuzzy normed spaces. Our results improve and restate the proof lines of the main results given in the papers (Eshaghi Gordji et al. in Math. Comput. Model. 54:1897-1906, 2011) and (Sintunavarat et al. in Fixed Point Theory Appl.

Common coupled coincidence and coupled fixed point results in two generalized metric spaces [PDF]
Fixed Point Theory and Applications, 2011 AbstractIn this article, we prove the existence of common coupled coincidence and coupled fixed point of generalized contractive type mappings in the context of two generalized metric spaces. These results generalize several comparable results from the current literature.

Some strong coupled coincidence and coupled best proximity results on complete metric spaces
Journal of Inequalities and ApplicationsIn this paper, the concept of Wardowski’s class of contraction is integrated with that of g-coupling to define some F-contractive type g-couplings. We establish existence results for a coupled coincidence point, a strong coupled coincidence point, and a ...

Coupled and Tripled Coincidence Point Results with Application to Fredholm Integral Equations [PDF]
Abstract and Applied Analysis, 2014 The aim of this paper is to define weak α-ψ-φ-contractive mappings and to establish coupled and tripled coincidence point theorems for such mappings defined on Gb-metric spaces using the concept of rectangular G-α-admissibility.

On Strong Coupled Coincidence Points of g-Couplings and an Application [PDF]
Journal of Function Spaces, 2018 The purpose of this paper is to prove the existence and uniqueness of a strong coupled coincidence point of F:X×X→X and g:X→X, involving Banach and Chatterjea type g-couplings.

Fixed Point Theory and Applications, 2010 Let \(X\) be a nonempty set and \(F:X\times X\rightarrow X\), \(g:X\rightarrow X\) be two mappings. An ordered pair \((x,y)\in X\times X\) is called: (i) a coupled coincidence point of \(\{F,g\}\) if \(g(x)=F(x,y)\) and \(g(y)=F(y,x)\); (ii) a common coupled coincidence point of \(\{F,g\}\) if \(x=g(x)=F(x,y)\) and \(y=g(y)=F(y,x)\).
