Homogeneous abelian groups
We obtain a description of homogeneous groups for arbitrary periodic abeliangroups and arbitrary torsion-free abelian groups, and also for the case when the periodic part T(A) of group A splits into a finite direct sum of primary components. In addition, homogeneous groups from the principal universal class in Aρ are described, where Aρ is the class of abelian groups A whose periodic part T(A) is a p-group.
