Abstract.

Let G be a torsion-free abelian group and n be a (finite) cardinal. The group G is called n-QE-transitive if for any pure subgroups X,Y of rank n of G, there exists some endomorphism ϕ of G such that ϕ(X)Y and Y/ϕ(X) is a torsion abelian group. We investigate these groups and obtain results similar to the ones for E-transitive groups.

Keywords: QE-transitive torsion-free abelian groups; Q-separable groups
