Abstract
Totally transitive torsion-free groups all non-zero endomorphisms of which are monomorphisms are studied. Such are characterized in terms of modules over some rings with specific properties. Also, a structural description is provided for quasihomogeneous, totally transitive, torsion-free groups \(A\) of finite \(p\)-rank, for at least one prime \(p\) not dividing \(A\).
