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 ...

Teori Titik Tetap untuk Tipe Kannan yang Diperumum dalam Ruang b-Metrik Modular Lengkap

open access: yesJambura Journal of Mathematics, 2023
Some generalizations of Banach's contraction principle, which is a fixed-point theorem for contraction mapping in metric spaces, have developed rapidly in recent years.

On a new generalization of metric spaces [PDF]

open access: yesJournal of Fixed Point Theory and Applications, 2018
In this paper, we introduce the $${\mathcal {F}}$$F-metric space concept, which generalizes the metric space notion. We define a natural topology $$\tau _{{\mathcal {F}}}$$τF in such spaces and we study their topological properties.

Multiembedding of Metric Spaces [PDF]

open access: yesSIAM Journal on Computing, 2004
Metric embedding has become a common technique in the design of algorithms. Its applicability is often dependent on how high the embedding's distortion is. For example, embedding finite metric space into trees may require linear distortion as a function of its size.

Compactness in Metric Spaces [PDF]

open access: yesFormalized Mathematics, 2016
Summary In this article, we mainly formalize in Mizar [2] the equivalence among a few compactness definitions of metric spaces, norm spaces, and the real line. In the first section, we formalized general topological properties of metric spaces.

Some remarks concerning D∗-metric spaces

open access: yes, 2020
In this note we make some remarks concerning D{metric spaces, and present some examples which show that many of the basic claims concerning the topological structure of such spaces are incorrect, thus nullifying many of the results claimed for these ...

Some Fixed-Circle Theorems on Metric Spaces [PDF]

open access: yesBulletin of the Malaysian Mathematical Sciences Society, 2017
The fixed-point theory and its applications to various areas of science are well known. In this paper, we present some existence and uniqueness theorems for fixed circles of self-mappings on metric spaces with geometric interpretation.

Some New Aspects in the Intuitionistic Fuzzy and Neutrosophic Fixed Point Theory

open access: yesJournal of Function Spaces, 2022
In this manuscript, we use the concepts of continuous t-norms and continuous t-conorms to introduce some definitions, in which intuitionistic fuzzy rectangular metric spaces, intuitionistic fuzzy rectangular metric-like spaces, intuitionistic fuzzy ...

An inequality in metric spaces [PDF]

open access: yes, 2004
In this note we establish a general inequality valid in metric spaces that is related to the polygonal inequality and admits also a natural geometrical interpretation.
