On partial metric spaces and partial cone metric spaces

open access: yesHacettepe Journal of Mathematics and Statistics, 2017
It this article we shall show that partial metric spaces and partial cone metric spaces are quasi-uniformizable and hence quasi-metrizable. Finally, an application to the Banach’s fixed point theorem will be presented in this context.

Some Modified Fixed Point Results in V-Fuzzy Metric Spaces

open access: yesAdvances in Fuzzy Systems, 2019
The present research paper focuses on the existence of fixed point in V-fuzzy metric space. The presentation of V-fuzzy metric space in n-tuple encourages us to define different mapping in the symmetric V-fuzzy metric space. Here, the properties of fuzzy

Fixed Point Theorems in Complex Valued B-Metric Spaces

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2017
A complex-valued b-metric space is a generalization of a b-metric space in which its b-metric space has complex value. It can also be considered as a generalization of a complex-valued metric space. Hence, fixed point theorems that have been studied in b-

Fixed-Point Theorems for Nonlinear Contraction in Fuzzy-Controlled Bipolar Metric Spaces

open access: yesAxioms, 2023
In this paper, we introduce the concept of fuzzy-controlled bipolar metric space and prove some fixed-point theorems in this space. Our results generalize and expand some of the literature’s well-known results.

open access: yes, 2013
Existence and uniqueness of fixed points are established for a mapping satisfying a contractive condition involving a rational expression on a generalized metric space.

Some results for multivalued mappings in extended fuzzy b-metric spaces

open access: yesAIMS Mathematics, 2023
In this paper, some fixed point results for multivalued contractions are established in setting G-complete extended fuzzy b-metric spaces. An example is furnished to demonstrate the validity of results.

Function valued metric spaces [PDF]

open access: yesSurveys in Mathematics and its Applications, 2010
In this paper we introduce the notion of an ℱ-metric, as a function valued distance mapping, on a set X and we investigate the theory of ℱ-metrics paces.
