On boundedly-convex functions on pseudo-topological vector spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Notions of a boundedly convex function and of a Lipschitz-continuous function are extended to the case of functions on pseudo-topological vector spaces.

Formalization of the Equivalence among Completeness Theorems of Real Number in Coq

open access: yesMathematics, 2020
The formalization of mathematics based on theorem prover becomes increasingly important in mathematics and computer science, and, particularly, formalizing fundamental mathematical theories becomes especially essential.

A quasitopos containing CONV and MET as full subcategories

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
We show that convergence spaces with continuous maps and metric spaces with contractions, can be viewed as entities of the same kind. Both can be characterized by a “limit function” λ which with each filter ℱ associates a map λℱ from the underlying set ...

Convergence of space and time through GIS [PDF]

open access: yesGlasnik Srpskog Geografskog Društva, 2023
Human's exploration of space has changed over time, depending on the expansion of the limits of his knowledge. Space is infinite, but it is limited by the possibility of human knowledge. The original man knew very little about the space in which

Compactifications of convergens spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
This paper summarizes most of the results to date on convergence space compactifications, and establishes necessary and sufficient conditions for the existence of largest and smallest compactifications subject to various conditions imposed upon the ...

Tuning Multiple Fano Resonances for On-Chip Sensors in a Plasmonic System

open access: yesSensors, 2019
This paper proposed a plasmonic resonator system, consisting of a metal-insulator-metal structure and two stubs, and a Fano resonance arose in its transmittance, which resulted from the coupling between the two stubs.

Convergence in variable Lebesgue spaces [PDF]

open access: yesPublicacions Matemàtiques, 2010
We consider the relationship in the variable Lebesgue space Lp(·)(Ω) between convergence in norm, convergence in modular, and convergence in measure, for both bounded and unbounded exponent functions.

Separation axioms for partially ordered convergence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
In partially ordered convergence spaces, separation axioms are introduced and then related to the concept of complete separatedness due to Nachbin as well as to connectedness concepts. A method to generate new separation axioms is studied.

T0 convergence-approach spaces

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2020
Summary: In previous papers, several \(T_0\)-objects in set-based topological category have been introduced and compared. In this paper, we give the characterization of general \(\overline{T_0}\) (resp. \(T_0\), and \(T_0^\prime\)) convergence approach spaces as well as show how these notions are linked to each other.

A class of completely regular spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
In this paper we investigate topologies with ultrafilters having bases of open sets. It is shown that these topologies are completely regular. All results are obtained by using Richardson's compactification of convergence spaces.
