Commutator Invariant Subgroups of Abelian Groups

Siberian Mathematical Journal, 2010
The commutator \([\varphi,\psi]\) of two elements of a ring is the element \(\varphi\psi-\psi\varphi\). A subgroup \(H\) of an Abelian group \(A\) is commutator invariant if \([\varphi,\psi]H\subseteq H\) for all commutators in the endomorphism ring of \(A\).

Pure subgroups of non-abelian groups

Publicationes Mathematicae Debrecen, 2022
A footnote to this paper explains that it was written in 1961 and is now published to complete the record of the mathematical work of the late A. Kertész. Let n be a cardinal number. A subgroup G of a group H is called n-pure if every system of equations in the elements of G and a set of variables X with \(| X|

SOLUTION TO THE UNIFORMLY FULLY INERT SUBGROUPS PROBLEM FOR ABELIAN GROUPS

Rocky Mountain Journal of Mathematics, 2023
A famous conjecture attributed to Dardano-Dikranjan-Rinauro-Salce states that any uniformly fully inert subgroup of a given group is commensurable with a fully invariant subgroup (see, respectively, [5] and [6]).
