On the topological covering properties by means of generalized open sets

open access: yesTopological Algebra and its Applications, 2023
By utilizing gg-open sets, we developed the ideas of GO-Mengerness and GO-Lindelöfness in this article. The structure of GO-compactness is compared to these topological covering features.

A criterion of the existence of an embedding of a monothetic monoid into a topological group

open access: yesTopological Algebra and its Applications, 2019
Using properties of unitary Cauchy filters on monothetic monoids, we prove a criterion of the existence of an embedding of such a monoid into a topological group.

Ordered sets as uniformities

open access: yesTopological Algebra and its Applications, 2018
In [7] a relation between completeness of certain uniformity on ordered sets and restrictions of homeomorphisms of compactifications is described. We shall add more details here and correct one proof.

A measure of non-compactness on T 3½ spaces based on Arzelà-Ascoli type theorem

open access: yes, 2021

A smooth compactification of spaces of stability conditions: the case of the $A_{n}$ -quiver

open access: yesForum of Mathematics, Sigma
We propose a notion of multi-scale stability conditions with the goal of providing a smooth compactification of the quotient of the space of projectivized Bridgeland stability conditions by the group of autoequivalence.

Countable Compactifications and a Generalized Hahn-Mazurkiewicz Type Theorem

open access: yes, 1996
In this paper, we provide a characterization as to when a locally connected generalized continuum (a locally compact connected separable metric space) has a countable compactification of a certain order type.

Bohr Topologies and Partition Theorems for Vector Spaces

open access: yes, 1997
We prove a Ramsey-style theorem for sequences of vectors in an infinite-dimensional vector space over a finite field. As an application of this theorem, we prove that there are countably infinite Abelian groups whose Bohr topologies are not homeomorphic.

Generalized Symmetric Rational Contraction Principle in Metric Space

open access: yes, 2020
Our aim of this paper is to introduced the concept of week symmetric rational contraction principle in metric space and prove some fixed point theorems in metric spaces. Our results are generalization and extended some previous known results.

Alignments of Radio Source in the ELAIS N1 Deep Field

open access: yes, 2014
Results of the AGN jets position angle alignments in the ELAIS N1 Deep radio survey are presented here. The ELAIS N1 deep radio survey was carried out with the Giant Meter- wave Radio Telescope at 615 MHz.

A characterization of the prime closed filter compacttification of a topological space

open access: yes, 2002
Dedicated to our friends and fellow-topologists Eraldo Giuli, Mirek Hušek, and Gerhard Preuss on the occasion of their 60th birthday. The prime compactification whose points are the prime closed filters can be defined for a general topological space and ...
