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.
