Relation-Theoretic Contraction Principle In Metric Spaces Using Multiplicative Contraction

open access: yesRatio Mathematica, 2023
Alam and Imdad have presented a novel application of the Banach contraction principle on a complete metric spaces with a binary relation. We have extended the concept of binary relation with the multiplicative contraction in a complete metric spaces.

A new approach on generalized quasimetric spaces induced by partial metric spaces

open access: yesJournal of Inequalities and Applications, 2022
In this paper, we introduce the concept of generalized quasimetric spaces by a new approach, and present some examples in the partial metric spaces. Furthermore, we obtain some results on (strong) complete partial metric spaces.

New Results on F-Contractions in Complete Metric Spaces

open access: yesMathematics, 2021
The main purpose of this paper is to improve, generalize, unify, extend and enrich the recent results established by Dung and Hang (2015), Piri and Kumam (2014, 2016), and Singh et al. (2018). In our proofs, we only use the property (F1) of Wardowski’s F-

On d*-Complete Topological Spaces and Related Fixed Point Results

open access: yesMathematics, 2020
In this paper, we introduce the concept of d*-complete topological spaces, which include earlier defined classes of complete metric spaces and quasi b-metric spaces.

Fixed and common fixed points for $(psi,varphi)$-weakly contractive mappings in $b$-metric spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2017
In this paper, we give a fixed point theorem for $(psi,varphi)$-weakly contractive mappings in complete $b$-metric spaces. We also give a common fixed point theorem for such mappings in complete $b$-metric spaces via altering functions. The given results

Some Extensions of Fixed Point Results over Quasi-JS-Spaces

open access: yesJournal of Function Spaces, 2016
We introduce the notion of quasi-JS-metric space. After defining the basic topological properties of quasi-JS-metric space, we investigate fixed point of certain mapping in the frame of complete quasi-JS-metric space.

Generalized Metric Spaces Do Not Have the Compatible Topology

open access: yesAbstract and Applied Analysis, 2014
We study generalized metric spaces, which were introduced by Branciari (2000). In particular, generalized metric spaces do not necessarily have the compatible topology.

Order isomorphisms between bases of topologies

open access: yesExtracta Mathematicae, 2022
In this paper we will study the representations of isomorphisms between bases of topological spaces. It turns out that the perfect setting for this study is that of regular open subsets of complete metric spaces, but we have been able to show some ...

Meir–Keeler Fixed-Point Theorems in Tripled Fuzzy Metric Spaces

open access: yesMathematics, 2023
In this paper, we first propose the concept of a family of quasi-G-metric spaces corresponding to the tripled fuzzy metric spaces (or G-fuzzy metric spaces). Using their properties, we give the characterization of tripled fuzzy metrics.
