Some Characterizations of Complete Hausdorff KM-Fuzzy Quasi-Metric Spaces [PDF]

Mathematics, 2023
Gregori and Romaguera introduced, in 2004, the notion of a KM-fuzzy quasi-metric space as a natural asymmetric generalization of the concept of fuzzy metric space in the sense of Kramosil and Michalek.

Existence of Fixed Points of Suzuki-Type Contractions of Quasi-Metric Spaces

Mathematics, 2023
In order to generalize classical Banach contraction principle in the setup of quasi-metric spaces, we introduce Suzuki-type contractions of quasi-metric spaces and prove some fixed point results.

On Hybrid Contractions in the Context of Quasi-Metric Spaces

Mathematics, 2020
In this manuscript, we will investigate the existence of fixed points for mappings that satisfy some hybrid type contraction conditions in the setting of quasi-metric spaces. We provide examples to assure the validity of the given results. The results of

Fuzzy quasi-metric spaces

Applied General Topology, 2004
We generalize the notions of fuzzy metric by Kramosil and Michalek, and by George and Veeramani to the quasi-metric setting.We show that every quasi-metric induces a fuzzy quasi-metric and ,conversely, every fuzzy quasi-metric space generates a quasi ...

Double Controlled Quasi Metric Like Spaces

Symmetry, 2022
In this article, we present a generalization of the double controlled metric like spaces, called quasi double controlled metric like spaces, by assuming that the symmetric condition is not necessary satisfied. Moreover, the self distance is not necessary zero.

On surrounding quasi-contractions on non-triangular metric spaces

Open Mathematics, 2020
The aim of this paper is to establish some fixed point results for surrounding quasi-contractions in non-triangular metric spaces. Also, we prove the Banach principle of contraction in non-triangular metric spaces.

Expansive homeomorphisms on quasi-metric spaces

Applied General Topology
The investigation of expansive homeomorphisms in metric spaces began with Utz in 1950. Thereafter, several authors have extensively studied this concept for different motivations.

Quasi-Partial Branciari b-Metric Spaces and fixed point results with an application [PDF]

Journal of Hyperstructures, 2023
The main aim of this research paper is to introduce concept of quasi-partial Branciari b-metric space. Such spaces arean extension of quasi-partial metric spaces, quasi-partial b-metric spaces and quasi-partial Branciari metric spaces.

Fixed point theorems for generalized ( α , ψ ) $(\alpha ,\psi )$ -contraction mappings in rectangular quasi b-metric spaces

Fixed Point Theory and Algorithms for Sciences and Engineering, 2022
In this paper, we introduce the class of rectangular quasi b-metric spaces as a generalization of rectangular metric spaces, rectangular quasi-metric spaces, rectangular b-metric spaces, define generalized ( α , ψ ) $(\alpha ,\psi ) $ -contraction ...
