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 \(y=g(y)=F(y,x)\).

Coupled coincidence point results for contraction of $C$-class mappings in ordered uniform spaces
Karpatsʹkì Matematičnì Publìkacìï, 2019 In the literature there is a lot of works related to fixed point theory. The theory has many applications and some authors are interested in these applications in various spaces. In 2009, Altun I. and Imdad M. defined the order relation on uniform spaces

MULTIVALUED COUPLED COINCIDENCE POINT RESULTS IN METRIC SPACES
Matematički Vesnik, 2023 Summary: In this paper, we use an inequality involving a coupled multivalued mapping and a singlevalued mapping to obtain a coupled coincidence point theorem. We discuss special conditions under which coupled common fixed point theorems are obtained. The result combines several ideas prevalent in fixed point theory studies.

A New Technique to Compute Coupled Coincidence Points [PDF]
Chinese Journal of Mathematics, 2014 We compute coupled coincidence points without assuming the condition of compatibility of the pair of maps and relaxing the continuity condition of both the maps. In fact, our technique improves the technique introduced by Sintunavarat et al. (2011) which was then used by Hussain et al. (2012) to obtain coupled coincidence points.

Fixed point results of weakly contraction mappings in partially ordered b-metric spaces
BMC Research Notes, 2022 Objectives We explored the results of fixed point, coincidence point and coupled coincidence point for the mappings in an ordered metric spaces. Our results generalized and extended the well-known results in the literature.

Some Fixed Point Theorems in Generalized Metric Spaces Endowed with Vector-valued Metrics and Application in Linear and Nonlinear Matrix Equations [PDF]
Sahand Communications in Mathematical Analysis, 2020 Let $mathcal{X}$ be a partially ordered set and $d$ be a generalized metric on $mathcal{X}$. We obtain some results in coupled and coupled coincidence of $g$-monotone functions on $mathcal{X}$, where $g$ is a function from $mathcal{X}$ into itself ...

Fixed point results for weak contractions in partially ordered b-metric space
BMC Research Notes, 2021 Objectives We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered b-metric space using a generalized $$({\check{\psi }}, \hat{\eta })$$ ( ψ ˇ , η ^ ) -weak contraction.
