Factorization properties of paratopological groups

open access: yesTopology and its Applications, 2013
The paper under review answers in the affirmative several questions on the \(\mathbb{R}\)-factorizability of paratopological groups (and related properties) posed in [\textit{M. Sanchis} and \textit{M. Tkachenko}, Topology Appl. 157, No. 4, 800--808 (2010; Zbl 1185.54034)] and [\textit{L.-H. Xie} and \textit{S. Lin}, Topology Appl. 160, No. 8, 979--990

On H-closed paratopological groups

open access: yes, 2010
A Hausdorff paratopological group G is H-closed if G is closed in each Hausdorff paratopological group containing G. We obtain criteria of H-closedness for some classes of abelian paratopological groups. In particular, for topological groups.

Mapping i2 on the free paratopological groups

open access: yesPublications de l'Institut Mathematique, 2017
Let FP(X) be the free paratopological group over a topological space X. For each nonnegative integer n ? N, denote by FPn(X) the subset of FP(X) consisting of all words of reduced length at most n, and in by the natural mapping from (X ? X?1 ? {e})n to FPn(X). We prove that the natural mapping i2:(X ? X?1 d ?{e})2 ?

Bornoligies, Topological Games and Function Spaces [PDF]

open access: yes, 2014
In this paper, we continue the study of function spaces equipped with topologies of (strong) uniform convergence on bornologies initiated by Beer and Levi \cite{beer-levi:09}.

The extensions of paratopological groups

open access: yesTopology and its Applications, 2015
A \textit{paratopological} group is a pair \((G,\mathcal T)\) consisting of a group \(G\) and a topology \(\mathcal T\) on it such that the multiplication is continuous (in other words, \((G,\mathcal T)\) is a topological semigroup). The authors study the following general problem: ``Let \(\mathcal P\) be a (topological, algebraic, or a mixed nature ...

Dense subgroups of paratopological groups

open access: yesTopology and its Applications, 2015
A paratopological group (semitopological group) is a group with a topology such that the multiplication operation is jointly (separately) continuous. In this paper, the author focus on some properties in semitopological groups which are preserved or determined by dense subgroups. Many propositions for this kind of properties are given. For example, (1)

Productivity numbers in paratopological groups

open access: yesTopology and its Applications, 2015
A \textit{paratopological group} \(G\) is a group endowed with a topology on \(G\) such that the mapping \((x, y) \mapsto xy\) of \(G\times G\) into \(G\) is continuous. If in addition, the mapping \(x \mapsto x^{-1}\) of \(G\) into \(G\) is continuous then \(G\) is a \textit{topological group}. In this article, the authors investigate the preservation
