*Junior Kolloquium*

*Univ. Prof. Dr. Arhangelskii: „An introduction to Hausdorff 
compactifications of topological spaces”*

* *

Abstract: "Some basic definitions and facts involving Hausdorff 
compactifications of Tychonoff spaces are exposed. In particular, we 
briefly discuss extensions of continuous mappings of spaces to their 
compactifications.

We also present some elementary duality theorems relating certain 
properties of a space to some properties of its remainders. Several 
examples are thoroughly discussed."

*Univ. Prof. Dr. Arhangelskii: “Remainders of non-locally compact 
topological groups in Hausdorff compactifications”***

Abstract: A Hausdorff compactification of a topological space $X$ is a 
compact Hausdorff space $bX$ which contains $X$ as a dense subspace. If 
$G$ is a topological group, and $bG$ is a Hausdorff compactification of 
the space $G$, then the subspace $rG=bG\setminus G$ is called a 
remainder of $G$. If $G$ is locally compact, then $rG$ is compact. If 
$G$, in addition, is not compact, then $rG$ can be selected to be a 
singleton, that is, to be trivial.

We consider a more delicate case of a non-locally compact topological 
group $G$ and discuss, when some remainder $rG$ of $G$ is metrizable, 
when some remainder of $G$ is paracompact, when some $rG$ has the Baire 
property, and some other questions on relationship between topological 
properties of $G$ and $rG$. In particular, a necessary and sufficient 
condition, in terms of remainders, for a non-locally compact topological 
group to be separable and metrizable is provided.

The case of remainders of paratopological groups is also briefly 
considered. It is shown that some basic results on remainders of 
topological groups cannot be extended to paratopological groups.
