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.

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 ...

Mathematics, 2018 In this paper, in the setting of Δ -symmetric quasi-metric spaces, the existence and uniqueness of a fixed point of certain operators are scrutinized carefully by using simulation functions.

Expansive homeomorphisms on quasi-metric spaces
Applied General TopologyThe investigation of expansive homeomorphisms in metric spaces began with Utz in 1950. Thereafter, several authors have extensively studied this concept for different motivations.

On Intuitionistic Fuzzy Quasi Metric Space
Al-Mustansiriyah Journal of Science, 2022 In this article the fixed point of intuitionistic fuzzy quasi metric space instabilities on two metrics dx(f, g) and Dx(f, g) on complicity space X have been studied and presented in details depended on (0,1]-fuzzy contractive map.

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.

A Few Notes on Formal Balls [PDF]
Logical Methods in Computer Science, 2017 Using the notion of formal ball, we present a few new results in the theory of quasi-metric spaces. With no specific order: every continuous Yoneda-complete quasi-metric space is sober and convergence Choquet-complete hence Baire in its $d$-Scott ...

A Discussion on p-Geraghty Contraction on mw-Quasi-Metric Spaces
Mathematics, 2020 In this paper we consider a kind of Geraghty contractions by using mw-distances in the setting of complete quasi-metric spaces. We provide fixed point theorems for this type of mappings and illustrate with some examples the results obtained.

Bourbaki completeness in quasi metric spaces [PDF]
Journal of Nonlinear Functional Analysis, 2019 The main purpose of this paper is to define a new type of boundedness in a quasi metric space. We introduce some new notions of completeness by clustering sequences belonging to the classes larger than the classes of Cauchy sequences in some sense. We also obtain some interesting results related to the compactness.
