A Note on the Square Subgroups of Decomposable Torsion-Free Abelian Groups of Rank Three
A hypothesis stated in [16] is confirmed for the case of associative rings. The answers to some questions posed in the mentioned paper are also given. The square subgroup of a completely decomposable torsion-free abelian group is described (in both cases of associative and general rings). It is show...
