Concepts of general topology in constructive mathematics and in sheaves, II

open access: closedAnnals of Mathematical Logic, 1982
AbstractTopological properties of spaces of sections of bundles are investigated in detail, and connected with results in constructive topology, in particular for notions of compactness, connectedness and uniformity.

Topology and life: In search of general mathematical principles in biology and sociology [PDF]

open access: closedThe Bulletin of Mathematical Biophysics, 1954
Mathematical biology has hitherto emphasized the quantitative, metric aspects of the physical manifestations of life, but has neglected the relational or positional aspects, which are of paramount importance in biology. Although, for example, the processes of locomotion, ingestion, and digestion in a human are much more complex than in a protozoan, the

Digital Experiences of Mathematical Cognitive Functions in Learning the Basic Concepts of General Topology

open access: hybridInternational Journal of Research in Undergraduate Mathematics Education
AbstractThis paper aims at defining and exploring design principles in a distance technological setting for an educational activity for mathematics undergraduate students, devoted to the construction of basic concepts in general topology, the promotion of problem-solving processes, the development of metacognitive aspects, and, in general, the ...

Topological Essence of the Concept "Limit of a Function" in the General Mathematics [PDF]

open access: yesRA JOURNAL OF APPLIED RESEARCH, 2021
ABSTRACT: The limit of a function is one of the most important concepts in high school mathematics. But unfortunately, not many students understand the essence of this concept. They had to accept it. This paper presents the topological essence of a limit of a function and discusses methods for teaching this concept in general education in Viet Nam.

Topological Essence of the Concept "Limit of a Numerical Sequence" in the General Mathematics

open access: yesRA JOURNAL OF APPLIED RESEARCH, 2021
ABSTRACT: High school mathematics includes a number of extremely important concepts, including the concept of the limit of the number sequence. However, most students when learning it do not understand it with certainty, but only accept it to apply it to solve exercises.

Fundamental properties of fuzzy rough sets based on triangular norms and fuzzy implications: the properties characterized by fuzzy neighborhood and fuzzy topology

open access: yesComplex & Intelligent Systems, 2023
Fuzzy rough set models are useful tools for dealing with fuzzy and real-valued data. They have been used in many real-world applications. In this paper, we investigate the fuzzy rough set model based on triangular norms and fuzzy implications.

Mathematical modeling and visualization of topologically non-trivial solutions in general relativity [PDF]

open access: yesJournal of Physics: Conference Series, 2021
Abstract In general relativity, there is a class of solutions that currently do not have observed analogues, but on which the theory is shaped, giving an understanding what is fundamentally possible within its framework. Such solutions include wormholes, tunnels that connect distant regions in spacetime.
