Abstract:
Let A be a torsion-free abelian group of rank one or two. We use the type set of A to give necessary and sufficient conditions for the subgroups of A to be ideals in every ring on A.
Keywords:
ring over an Abelian group, nil group, torsion-free group, strongly nil subgroup, strongly non-nil subgroup.
