Schur ultrafilters and Bohr compactifications of topological groups
Serhii Bardyla, Pavol Zlatoš
In this paper we investigate Schur ultrafilters on groups. Using the algebraic structure of Stone-Čech compactifications of discrete groups and Schur ultrafilters, we give a new de…

The Bohr compactification of an abelian group as a quotient of its Stone-Čech compactification
Pavol Zlatoš
We will prove that, for any abelian group , the canonical (surjective and continuous) mapping from the Stone-Čech compactification …
