Pure Subgroups of Torsion-Free Groups

In this paper, we show that certain new notions of purity stronger than the classical concept are relevant to the study of torsion-free abelian groups. In particular, implications of $\ast$-purity, a concept introduced in one of our recent papers, are investigated. We settle an open question... Full description
