Common coupled fixed point theorems for two pairs of weakly compatible mappings in Menger metric spaces

Moroccan Journal of Pure and Applied Analysis, 2019
In this paper, we prove some common coupled fixed point theorems for contractive mappings in Menger metric spaces under geometrically convergent t-norms. Also, we prove common fixed point theorems for pairs of weakly compatible mappings, which generalize

On Almost (α, θρ)‐Contractions on Quasimetric Space and Their Fixed Points

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we introduce the concept of almost (α, θρ)‐contraction mappings on quasimetric spaces. Then, under certain conditions, we present some fixed‐point results for almost (α, θρ)‐contraction mappings with respect to ω and γ on both left K‐complete and left M‐complete quasimetric spaces.

Common fixed points of almost generalized (ψ,φ)s-contractive mappings in ordered b-metric spaces

, 2013
In this paper, we introduce the notion of almost generalized (ψ,φ)s-contractive mappings and we establish some fixed and common fixed point results for this class of mappings in ordered complete b-metric spaces.

Dislocated quasi cone b-metric space over Banach algebra and contraction principles with application to functional equations

Open Mathematics, 2019
In this paper we introduce dislocated and dislocated quasi version of a cone b-metric space over a Banach algebra as well as weak semi α-admissible and α-identical pair of mappings and prove common fixed point theorems for a pair of α-identical and weak ...

Common Fixed Point Theorems for Order Contractive Mappings on a σ‐Complete Vector Lattice

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we prove some common fixed point theorems for order contractive mappings on a σ‐complete vector lattice. We apply new results to study the well‐posedness of a common fixed point problem for two contractive mappings. Our proofs are simple and purely order‐theoretic in nature.

Discussion on some coupled fixed point theorems

, 2013
In this paper, we show that, unexpectedly, most of the coupled fixed point theorems (on ordered metric spaces) are in fact immediate consequences of well-known fixed point theorems in the literature.MSC: 47H10, 54H25.

Coincidence Point Results for Self‐Mapping With Extended Rational Contraction in Partially Ordered Ultrametric Spaces Using p‐Adic Distance

Journal of Mathematics, Volume 2024, Issue 1, 2024.
This paper aims to investigate new coincidence point theorems for self‐maps under an extended rational contraction. Our approach uses the p‐adic distance in partially ordered ultrametric spaces. Furthermore, to illustrate our major discoveries, we give a comprehensive numerical analysis.

Tripled best proximity point in complete metric spaces

Open Mathematics, 2020
In this paper, we introduce a new type of contraction to seek the existence of tripled best proximity point results. Here, using the new contraction and P-property, we generalize and extend results of W. Shatanawi and A. Pitea and prove the existence and
