Lipschitz groups and Lipschitz maps [PDF]

open access: yesInternational Journal of Group Theory, 2017
‎‎This contribution mainly focuses on some aspects of Lipschitz groups‎, ‎i.e.‎, ‎metrizable groups with Lipschitz multiplication and inversion map‎. ‎In the main result it is proved that metric groups‎, ‎with a translation-invariant metric‎, ‎may be ...

Predicting Emerging Themes in Rapidly Expanding COVID-19 Literature With Unsupervised Word Embeddings and Machine Learning: Evidence-Based Study

open access: yesJournal of Medical Internet Research, 2022
BackgroundEvidence from peer-reviewed literature is the cornerstone for designing responses to global threats such as COVID-19. In massive and rapidly growing corpuses, such as COVID-19 publications, assimilating and synthesizing ...

FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

open access: yesФізико-математична освіта, 2022
Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with

Localization of Dirac Fermions in Finite-Temperature Gauge Theory

open access: yesUniverse, 2021
It is by now well established that Dirac fermions coupled to non-Abelian gauge theories can undergo an Anderson-type localization transition. This transition affects eigenmodes in the lowest part of the Dirac spectrum, the ones most relevant to the low ...

Sensor Fusion for Social Navigation on a Mobile Robot Based on Fast Marching Square and Gaussian Mixture Model

open access: yesSensors, 2022
Mobile robot navigation has been studied for a long time, and it is nowadays widely used in multiple applications. However, it is traditionally focused on two-dimensional geometric characteristics of the environments. There are situations in which robots

A Topological Data Analysis approach for retrieving Local Climate Zones patterns in satellite data

open access: yesEnvironmental Challenges, 2021
In the context of geospatial studies, meaningful information may be hidden in the aspects of form and connectivity inscribed in the measurements. Therefore, here is proposed the use of H0 Persistent Homology (PH), a Topological Data Analysis tool to ...

On the Aspects of Enriched Lattice-valued Topological Groups and Closure of Lattice-valued Subgroups

open access: yesEuropean Journal of Pure and Applied Mathematics, 2021
Starting with L as an enriched cl-premonoid, in this paper, we explore some categorical connections between L-valued topological groups and Kent convergence groups, where it is shown that every L-valued topological group determines a well-known Kent convergence group, and conversely, every Kent convergence group induces an L-valued topological group ...

Topological aspect of monodromy groupoid for a group-groupoid

open access: yesFilomat, 2019
In this paper we develop star topological and topological group-groupoid structures of monodromy groupoid and prove that the monodromy groupoid of a topological group-groupoid is also a topological group-groupoid.

An adaptive and versatile method to quantitate and characterize collective cell migration behaviors on complex surfaces

open access: yesFrontiers in Cell and Developmental Biology, 2023
Collective cell migration is critical for proper embryonic development, wound healing, and cancer cell invasion. However, much of our knowledge of cell migration has been performed using flat surfaces that lack topographical features and do not ...

Some aspects of dimension theory for topological groups

open access: yesIndagationes Mathematicae, 2018
In this paper, the authors discuss dimension theory in the class of all topological groups. In the first section, they refer to the dawn of dimension theory in topology, in particular, introduce the research activities of Luitzen Egbertus Jan Brouwer (1881--1966) with Pavel Sergeyevich Alexandroff (1896--1982) and Pavel Samuilovich Urysohn (1898--1924).
