Fixed Point Theorems in Cone Metric Spaces via c-Distance Over Topological Module

open access: yesInternational Journal of Analysis and Applications, 2023
In 2011, Wang and Guo introduced c-distance in cone metric spaces. The idea of cone metric spaces over topological modules was presented by Branga and Olaru in 2020.

Some set-valued and multi-valued contraction results in fuzzy cone metric spaces

open access: yesJournal of Inequalities and Applications, 2021
This paper aims to present the concept of multi-valued mappings in fuzzy cone metric spaces and prove some basic lemmas, a Hausdorff metric, and fixed point results for set-valued fuzzy cone-contraction and for multi-valued fuzzy cone-contraction ...

Fixed point theorem between cone metric space and quasi-cone metric space

open access: yesIndonesian Journal of Electrical Engineering and Computer Science, 2022
This study involves new notions of continuity of mapping between quasi-cone metrics spaces (QCMSs), cone metric spaces (CMSs), and vice versa. The relation between all notions of continuity were thoroughly studied and supported with the help of examples.

g-Weak Contraction in Ordered Cone Rectangular Metric Spaces

open access: yesThe Scientific World Journal, 2013
We prove some common fixed-point theorems for the ordered g-weak contractions in cone rectangular metric spaces without assuming the normality of cone.

On the Paper: ''Examples in Cone Metric Spaces: A Survey'' Middle East Journal of Scientific Research, 11(12):1636-1640, 2014, M. Asadi, H. Soleimani [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2016
The paper ''Examples in Cone Metric Spaces: A Survey'' had overlooked the fact that -spaces are Banach spaces only for . Here, we show that, for , is not even a normed space .We also pointed out that the domain of the function of Example (1.17) of ...

Quasicone Metric Spaces and Generalizations of Caristi Kirk's Theorem

open access: yesFixed Point Theory and Applications, 2009
Cone-valued lower semicontinuous maps are used to generalize Cristi-Kirik's fixed point theorem to Cone metric spaces. The cone under consideration is assumed to be strongly minihedral and normal.

Results in Strongly Minihedral Cone and Scalar Weighted Cone Metric Spaces and Applications

open access: yesAnnales Mathematicae Silesianae, 2021
The convergence of sequences and non-unique fixed points are established in ℳ-orbitally complete cone metric spaces over the strongly minihedral cone, and scalar weighted cone assuming the cone to be strongly minihedral.

Cones of partial metrics

open access: yesContributions to Discrete Mathematics, 2011
A partial semimetric on a set X is a function (x,y)↦p(x,y)∈\RR≥0 satisfying p(x,y)=p(y,x), p(x,y)≥p(x,x) and p(x,z)≤p(x,y)+p(y,z)−p(y,y) for all x,y,z∈X. We study here the polyhedral convex cone PSMETn of all partial semimetrics on n points, using computations done for n≤6.

Common Coupled Fixed Point Theorems of Single-Valued Mapping for c-Distance in Cone Metric Spaces

open access: yesAbstract and Applied Analysis, 2012
The existence and uniqueness of the common coupled fixed point in cone metric spaces have been studied by considering different types of contractive conditions.
