On uniformly fully inert subgroups of abelian groups

open access: yesTopological Algebra and its Applications, 2020
If H is a subgroup of an abelian group G and φ ∈ End(G), H is called φ-inert (and φ is H-inertial) if φ(H) ∩ H has finite index in the image φ(H). The notion of φ-inert subgroup arose and was investigated in a relevant way in the study of the so called ...

Subgroup transitivity in abelian groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1998
We generalize an appropriate modification of the classical notion of transitivity in abelian p p -groups from one that is ...

Normalizers and centralizers of subgroups in non-Abelian groups of small order [PDF]

open access: yesКомпьютерные исследования и моделирование, 2012
By applying the computer program, which is created by authors, we obtain the exact representation of normalizers and centralizers of all nontrivial subgroups in non-Abelian groups G under the condition |G|20.

Groups with Finitely Many Isomorphism Classes of Non-Normal Subgroups [PDF]

open access: yesAdvances in Group Theory and Applications, 2020
We study groups in which the non-normal subgroups fall into finitely many isomorphism classes. We prove that a locally generalized radical group with this property is abelian-by-finite and minimax.

On T-Characterized Subgroups of Compact Abelian Groups

open access: yesAxioms, 2015
A sequence \(\{ u_n \}_{n\in \omega}\) in abstract additively-written Abelian group \(G\) is called a \(T\)-sequence if there is a Hausdorff group topology on \(G\) relative to which \(\lim_n u_n =0\).

Planarity of Inclusion Graph of Cyclic Subgroups of Finite Group [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
Let G be a finite group. The inclusion graph of cyclic subgroups of G, Ic(G), is the (undirected) graph with vertices of all cyclic subgroups of G, and two distinct cyclic subgroups ⟨a⟩ and ⟨b⟩, are adjacent if and only if ⟨a⟩ ⊂ ⟨b⟩ or ⟨b⟩ ⊂ ⟨a⟩. In this

n-capability of A-groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
Following P. Hall a soluble group whose Sylow subgroups are all abelian is called A-group. The purpose of this article is to give a new and shorter proof for a criterion on the capability of A-groups of order p2q, where p and q are distinct primes ...

Abelian Subgroups of Garside Groups [PDF]

open access: yesCommunications in Algebra, 2008
In this paper, we show that for every abelian subgroup $H$ of a Garside group, some conjugate $g^{-1}Hg$ consists of ultra summit elements and the centralizer of $H$ is a finite index subgroup of the normalizer of $H$. Combining with the results on translation numbers in Garside groups, we obtain an easy proof of the algebraic flat torus theorem for ...

Groups with many abelian subgroups

open access: yesJournal of Algebra, 2011
The authors classify all groups all of whose subgroups of infinite index are Abelian. This class of groups is closed with respect to subgroups and quotient groups (but not a formation). Main theorem: If \(G\) is a non-Abelian group as defined, then \(G\) is finitely generated and \textit{either} (a) \(G/Z(G)\) is a just-infinite group with no Abelian ...
