Feebly compact paratopological groups and real-valued functions [PDF]
We present several examples of feebly compact Hausdorff paratopological groups (i.e., groups with continuous multiplication) which provide answers to a number of questions posed in the literature.

Notes on Remainders of Paratopological Groups [PDF]
The remainder of a Tychonoff topological space \(X\) is the subspace \(bX\setminus X\) of some compactification \(bX\) of \(X\). The authors study remainders of paratopological and of semitopological groups \(G\), in particular they relate properties of \(G\) with properties of the remainder \(bG\setminus G\).

Baire property in product spaces
We show that if a product space $\mathit\Pi$ has countable cellularity, then a dense subspace $X$ of $\mathit\Pi$ is Baire provided that all projections of $X$ to countable subproducts of $\mathit\Pi$ are Baire.

p-Boundedness in paratopological groups
Let \(G\) be a paratopological group with neutral element \(e\). \(G\) is said to be \(\omega\)-admissible if for every sequence \(\{U_n:n\in\omega\}\) of open neighborhoods of \(e\) there there exists a subgroup \(H\subseteq\bigcap_{n\in\omega}U_n\) such that \(G/H\) is submetrizable. \(G\) is said to be \(\omega\)-balanced if for every neighborhood \(

The diagonal of a first countable paratopological group, submetrizability, and related results
We discuss some properties stronger than Gδ-diagonal. Among other things, we prove that any first countable paratopological group has a Gδ-diagonal of infinite rank and hence also a regular Gδ-diagonal.

On feebly compact paratopological groups [PDF]
We obtain many results and solve some problems about feebly compact paratopological groups. We obtain necessary and sufficient conditions for such a group to be topological. One of them is the quasiregularity. We prove that each $2$-pseudocompact paratopological group is feebly compact and that each Hausdorff $ $-compact feebly compact paratopological

Notes on paratopological groups
In this paper, all topological spaces are assumed to be Hausdorff. A paratopological group is a group with a topology such that the product operation is continuous. The paper contains two results: {\parindent=6mm \begin{itemize}\item[(1)] Let \(G\) be a paratopological group, \(bG\) a Hausdorff compactification of \(G\).
