An Alternative Proof of Hill's Criterion of Freeness for Abelian Groups
Palabras clave:
Abelian group, Freeness, Hill's criterion, G(\aleph_0)-family, Purity (es)
In this note we provide a different proof of Hill's criteria of freeness for abelian groups. Our proof hinges on the construction of suitable $G(\aleph_0)$-families of subgroups of the links in Hill's theorem and, ultimately, on the construction of such a family of pure subgroups of the group itself.
