On injective endomorphisms of the semigroup $B_{ω}^{F^{4}}$ with a four-element family $F^{4}$ of inductive non-empty subsets of $ω$

Oleg Gutik, Marko Serivka

We describe injective endomorphisms of the semigroup $B_{ω}^{F^{4}}$ with a four-element family $F^{4}$ of inductive non-empty subsets of $ω$ . In particu…

On semigroups which admit only discrete left-continuous Hausdorff topology

Oleg Gutik

We give the sufficient condition when every left-continuous (right-continuous) Hausdorff topology on a semigroup $S$ is discrete. We construct a submonoid $C_{+} (a, b)$ (r…
