An equivalence of results in $C^*$-algebra valued b-metric and b-metric spaces
Applied General Topology, 2017 We construct a $b$-metric from a given $C^*$-algebra-valued $b$-metric and prove some equivalences between them. Then we show that not only fixed point results but also topological properties on $C^*$-algebra-valued $b$-metric spaces may be deduced from ...

Some Equivalences between Cone b-Metric Spaces and b-Metric Spaces [PDF]
Abstract and Applied Analysis, 2013 We introduce a b-metric on the cone b-metric space and then prove some equivalences between them. As applications, we show that fixed point theorems on cone b-metric spaces can be obtained from fixed point theorems on b-metric spaces.

Integral Operators in b-Metric and Generalized b-Metric Spaces and Boundary Value Problems
Fractal and FractionalWe study fixed-point theorems of contractive mappings in b-metric space, cone b-metric space, and the newly introduced extended b-metric space. To generalize an existence and uniqueness result for the so-called Φs functions in the b-metric space to the ...

Annals of the West University of Timisoara: Mathematics and Computer Science, 2022 In this paper we present a new approach for the fuzzy quasi-b-metric spaces and we obtain some properties of these spaces. A special attention is granted to the decomposition theorems of a fuzzy quasi-b-metric into a right continuous and ascending family

Some Fixed Points Results in b-Metric and Quasi b-Metric Spaces
Journal of Function Spaces, 2022 We present a fixed point result in quasi b-metric spaces. Our result generalizes recent fixed point results obtained by Aleksić et al., Dung and Hang, Jovanović et al., Sarwar, and Rahman and classical results obtained by Hardy, Rogers, and Ćirić.

Existence of common fuzzy fixed points via fuzzy F-contractions in b-metric spaces [PDF]
Scientific ReportsThe main goal of this study is to establish common fuzzy fixed points in the context of complete b-metric spaces for a pair of fuzzy mappings that satisfy F-contractions.

Solution of fractional differential equations in quasi-b-metric and b-metric-like spaces [PDF]
Advances in Difference Equations, 2019 In this article, using by α-admissible and αqsp $\alpha _{qs^{p}}$-admissible mappings, solutions of some fractional differential equations are investigated in quasi-b-metric and b-metric-like spaces.

Basic inequality on a b-metric space and its applications. [PDF]
J Inequal Appl, 2017 We first prove one of the most basic inequalities on a b-metric space. And then we prove some fixed point theorems. We also consider two similar conditions; one implies the Cauchyness on sequences but the other does not.

On Fuzzy b-Metric-Like Spaces [PDF]
Journal of Function Spaces, 2021 The aim of this manuscript is to introduce the concept of fuzzy b-metric-like spaces and discuss some related fixed point results. Some examples are imparted to illustrate the feasibility of the proposed methods. Finally, to validate the superiority of the obtained results, an application is provided to solve a first kind of Fredholm type integral ...
