Finite rank torsion-free abelian groups uniserial over their endomorphism rings [PDF]
An abelian group is E E -uniserial if its lattice of fully invariant subgroups is totally ordered. Finite rank torsion-free reduced E E -uniserial groups are characterized. Such a group is a free module over the center C C of its endomorphism ring, and C C is a strongly ...

A matrix description for torsion free abelian groups of finite rank
We describe torsion free abelian groups of finite rank applying matrices with polyadic entries. This description can be considered as a modification of the classic description by A. I. Mal'cev.

The classification of torsion-free abelian groups of finite rank up to isomorphism and up to quasi-isomorphism [PDF]
The isomorphism and quasi-isomorphism relations on the $p$-local torsion-free abelian groups of rank $n\geq3$ are incomparable with respect to Borel reducibility.

Countable ℵ0-indecomposable mixed abelian groups of finite torsion-free rank
A group is \(\aleph_ 0\)-indecomposable if it cannot be decomposed into a direct sum of \(\aleph_ 0\) non-zero summands. In this paper the authors find necessary and sufficient conditions for an extension of a countable reduced torsion abelian group T by a finite rank torsion-free abelian group R to be \(\aleph_ 0\)-indecomposable. These conditions are
