On the product of finitely generated Abelian groups

Mathematical Notes of the Academy of Sciences of the USSR, 1973
It is shown that if a group G is a product of Abelian subgroups A and B one of which is finitely generated, then the group G will have a nontrivial normal subgroup that is contained either in A, or in B.

Finitely Generated Abelian Groups

1988
A group is finitely generated if it has a finite set of generators. Finitely generated abelian groups may be classified. By this we mean we can draw up a list (albeit infinite) of “standard” examples, no two of which are isomorphic, so that if we are presented with an arbitrary finitely generated abelian group, it is isomorphic to one on our list.

Abelian Subgroups of Finitely Generated Kleinian Groups are Separable

Bulletin of the London Mathematical Society, 1999
A subgroup \(H\) of \(G\) is called separable in \(G\) if it is an intersection of finite-index subgroups of \(G\). This generalizes the well-known property of residual finiteness, which is the condition that the trivial subgroup is separable in \(G\).
