On cut completions of abelian lattice ordered groups
Ján Jakubík (2000)
Czechoslovak Mathematical Journal
We denote by the class of all abelian lattice ordered groups such that each disjoint subset of is finite. In this paper we prove that if , then the cut completion of coincides with the Dedekind completion of .

On directed groups with additional operations
Ján Jakubík (1993)
Mathematica Bohemica
This paper deals with a question concerning -ideals of -groups which was proposed by V. M. Kopytov and Z. J. Dimitrov. We shall also investigate a class of -groups which is in a certain sense near to the class of all lattice ordered groups.

On half cyclically ordered groups
Ján Jakubík (2002)
Czechoslovak Mathematical Journal
In this paper we introduce and investigate the notion of half cyclically ordered group generalizing the notion of half partially ordered group whose study was begun by Giraudet and Lucas.
