Definition
A group is termed a finitely generated free abelian group if it satisfies the following equivalent conditions:
- It is isomorphic to a finite direct power of the group of integers, i.e., it is isomorphic to the group
for some positive integer
.
- It is the free abelian group on a finite generating set.
- It is the abelianization of a finitely generated free group.
- It is a finitely generated abelian group as well as a torsion-free abelian group.
