Gromov-Hausdorff compactness theorem for non-Archimedean fuzzy metric spaces

The authors introduced in a previous paper the notion of fuzzy Gromov-Hausdorff distance between non-Archimedean compact fuzzy metric spaces, presenting a fuzzy version of the Gromov's completeness theorem. In this paper we present a fuzzy version of the

Some Characteristics of Completeness Property in Fuzzy Soft b−Metric Space

Journal of Applied Science and Engineering
In this study, we developed a novel idea known as the fuzzy soft b-metric, and investigated some fundamental aspects of fuzzy soft b-metric. Moreover, various topological features of this new space, such as fuzzy soft open ball, and fuzzy soft Hausdorff ...

Ekeland’s variational principle for interval-valued functions with an α-level set in Kaleva-Seikkala’s type fuzzy metric spaces

Demonstratio Mathematica
In this paper, we establish a new version of Ekeland’s variational principle in the setting of Kaleva-Seikkala’s type fuzzy metric spaces, where the objective function is an interval-valued function defined on a fuzzy metric space, and the perturbation ...

Fixed-Point Results with Applications in Generalized Neutrosophic Rectangular b-Metric Spaces

Axioms
In this paper, we introduce several new concepts: generalized neutrosophic rectangular b-metric-like spaces (GNRBMLSs), generalized intuitionistic rectangular b-metric-like spaces (GIRBMLSs), and generalized fuzzy rectangular b-metric-like spaces ...
