finite abelian groups, subgroup lattices, fundamental group lattices, lattice isomorphisms

Abstract

The main goal of this note is to provide a new proof of a classical result about projectivity between finite abelian groups. It is based on the concept of fundamental group lattice, studied in our previous papers [8] and [9]. A generalization of this result is also given.
