Space of spaces as a metric space [PDF]

open access: yesCommunications in Mathematical Physics, 1999
In spacetime physics, we frequently need to consider a set of all spaces (`universes') as a whole. In particular, the concept of `closeness' between spaces is essential. However, there has been no established mathematical theory so far which deals with a

Fuzzy metric topology space and manifold [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2023
This paper, considers the fuzzy topological subsets, fuzzy topological spaces and introduces a novel concept of fuzzy Hausdorff space and fuzzy manifold space in this regards. Based on these concepts, we present a concept of fuzzy metric Hausdorff spaces

Probabilistic modular metric spaces [PDF]

open access: yesJournal of Hyperstructures, 2020
The purpose of this study is to investigate the connection between probabilistic and modular metric spaces. We discussseveral important properties such as convergence and completeness,etc, and the relationship among the mentioned properties in the ...

Pointwise k-Pseudo Metric Space

open access: yesMathematics, 2021
In this paper, the concept of a k-(quasi) pseudo metric is generalized to the L-fuzzy case, called a pointwise k-(quasi) pseudo metric, which is considered to be a map d:J(LX)×J(LX)⟶[0,∞) satisfying some conditions.

(L,M)-Fuzzy k-Pseudo Metric Space

open access: yesMathematics, 2022
Recently, the notion of a classical k-metric, which make the triangle inequality to a more general axiom: d(x,z)≤k(d(x,y)+d(y,z)), has been presented and is applied in many fields.

A metric for space [PDF]

open access: yesHippocampus, 2008
AbstractNot all areas of neuronal systems investigation have matured to the stage where computation can be understood at the microcircuit level. In mammals, insights into cortical circuit functions have been obtained for the early stages of sensory systems, where signals can be followed through networks of increasing complexity from the receptors to ...

From metric spaces to partial metric spaces [PDF]

open access: yesFixed Point Theory and Applications, 2013
Let \((X,p)\) be a partial metric space and \(p^s(x,y):= 2p(x,y)-p(x,x)-p(y,y) \) the metric on \(X\) generated by \(p\). In this paper the authors study the following problems: If \(T:(X,p) \to (X,p) \) is a generalized contraction, which condition satisfies \(T\) with respect to \(p^s\)?

Neutrosophic metric spaces [PDF]

open access: yesMathematical Sciences, 2020
In present paper, the definition of new metric space with neutrosophic numbers is given. Several topological and structural properties have been investigated. The analogues of Baire Category Theorem and Uniform Convergence Theorem are given for Neutrosophic metric spaces.
