摘要：

The notion of a near isomorphism is extended from finite-rank torsion-free Abelian groups to some classes of infinite-rank groups. The equivalence of different formulations of this notion for a certain class of countable-rank groups is proved. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
