Murley groups and the torsion-freeness of Ext

open access: yes, 2011
Let B be a torsion-free Abelian group of finite rank with OT(B)=type(Q). This paper gives necessary and sufficient conditions for such a group B to be a finitely faithful S-group with the property that every finite rank pure subgroup of a group A with ...

A torsion-free abelian group of finite rank exists whose quotient group modulo the square subgroup is not a nil-group

open access: yes, 2018
The first example of a finite rank torsion-free abelian group A such that the quotient group of A modulo the square subgroup of A is not a nil-group is indicated (in both cases of associative and general rings).
