On endoprimality of torsion-free abelian groups of rank 3
Acta Mathematica Hungarica, 2004Let \(A\) be a left \(R\)-module and \(n\in\mathbb{N}^*\). A function \(f\colon A^n\to A\) is an endofunction of \(A\) if \(\varphi(f(a_1,\dots,a_n))=f(\varphi(a_1),\dots,\varphi(a_n))\) for every endomorphism \(\varphi\) of \(A\) and for all \(a_1,\dots,a_n\in A\). We say that \(A\) is endoprimal if every endofunction of \(A\) is a term function which

POWER GROUPS OF FREE ABELIAN GROUPS OF FINITE RANK
Communications in Algebra, 2002ABSTRACT The power set of a group G has an induced semigroup structure, some subsets of which will form groups in their own right. We are especially interested in such subsets that are maximal. We demonstrate that even when G is a free abelian group of finite rank, the groups which arise in this way can be diverse profinite abelian groups.

Abelian automorphism groups of countable rank
1999The abelian automorphism groups of countable rank are largely determined. Those arising from automorphisms of torsion-free groups are completely determined.

The Non-Slender Rank of an Abelian Group
1984For a family (Ai)i∈I of Abelian groups and a cardinal K we define the K-product \(\mathop \Pi \limits_{i \in I} {A_i}\) to be the subgroup of the cartesian product \({\mathop \Pi \limits_I ^{(K)}}A\) consisting of all elements which support is less than K. Let us write AI(K) instead of \({A^{I(w)}} = \mathop \oplus \limits_I A\), A(I) instead of (math)
