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.

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

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 Multi-groups and Multi-fields [PDF]

open access: yes, 2009
Topological groups, particularly, Lie groups are very important in differential geometry, analytic mechanics and theoretical physics. Applying Smarandache multi-spaces, topological spaces, particularly, manifolds and groups were generalized to ...

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 ...

Topological Quantum Field Theory and the Geometric Langlands Correspondence [PDF]

open access: yes, 2013
In the pioneering work of A. Kapustin and E. Witten, the geometric Langlands program of number theory was shown to be intimately related to duality of GL-twisted N=4 super Yang-Mills theory compactified on a Riemann surface. In this thesis, we generalize

Topological Rough Groups

open access: yes, 2016
The concept of topological group is a simple combination of the concepts of abstract group and topological space. The purpose of this paper is to combine the concepts of topological space and rough groups; called topological rough groups on an ...

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 ...

Topological States of Matter [PDF]

open access: yes, 2012
My research program is focused on the study of elastic deformation and topological defects in two materials: graphene and topological insulators. In both systems at low energies the electrons have a nearly linear spectrum, i.e.

Deciphering the rhizosphere bacteriome associated with biological control of tobacco black shank disease

open access: yesFrontiers in Plant Science, 2023
IntroductionThe black shank disease seriously affects the health of tobacco plants. Conventional control methods have limitations in terms of effectiveness or economic aspects and cause public health concerns.
