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.

TEST ELEMENTS IN FINITELY GENERATED ABELIAN GROUPS

International Journal of Algebra and Computation, 2002
We determine which finitely generated abelian groups have test elements and give examples when they exist.

Tame automorphisms of finitely generated abelian groups

Proceedings of the Edinburgh Mathematical Society, 1998
We characterize tame automorphisms of finitely generated abelian groups via a simple determinant condition.

Systems Theory over Finitely Generated Abelian Groups

2000
A decision which has to be made in systems theory regards the choice of the space where the signals are assumed to take place. This is a crucial choice when we deal with continuous-time systems governed by non-linear or by partial differential equations while it becomes a less relevant issue when we are dealing with linear systems described by linear ...

Concerning automorphisms in finitely generated Abelian groups

Mathematical Proceedings of the Cambridge Philosophical Society, 1963
Of particular importance in the structure theory of finitely generated groups are those groups G having the property ℳd that for any two sets of generators g1, …, gd; h1, …, hd of G there is an automorphism θ of G such that (i = 1, …, d). Gaschütz(1) proved that all groups G having† ℳd also possess a further manifestation of symmetry, the property ...

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.

COHOMOLOGY OF FINITELY GENERATED ABELIAN GROUPS

1991
Let \(Q\) be a finitely generated abelian group and \(R\) a commutative ring. The author constructs a primitively generated cocommutative differential graded Hopf algebra \(A(Q)\) whose homology algebra is isomorphic, as \(R\)-algebra, to the cohomology ring of \(Q\).

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 \(G\).
