On closures in semitopological inverse semigroups with continuous inversion

open access: yes, 2014
We study the closures of subgroups, semilattices and different kinds of semigroup extensions in semitopological inverse semigroups with continuous inversion. In particularly we show that a topological group $G$ is $H$-closed in the class of semitopological inverse semigroups with continuous inversion if and only if $G$ is compact, a Hausdorff linearly ...

Filters and the weakly almost periodic compactification of a semitopological semigroup

open access: yes, 2013
Let $S$ be a semitopological semigroup. The $wap-$ compactification of semigroup S, is a compact semitopological semigroup with certain universal properties relative to the original semigroup, and the $Lmc-$ compactification of semigroup $S$ is a universal semigroup compactification of $S$, which are denoted by $S^{wap}$ and $S^{Lmc}$ respectively.

Ultrafilters on Semitopological Semigroups

Semigroup Forum, 2004
It has been known since the sixties that the Stone-Čech compactification of a discrete semigroup can be given a natural structure of a compact right topological semigroup. In [\textit{N. Hindman} and \textit{D. Strauss}, Algebra in the Stone-Čech compactification: theory and applications (de Gruyter Expositions in Mathematics 27) (1998; Zbl 0918.22001)]
