On groups satisfying the double chain condition on nonascendant subgroups [PDF]

open access: yesInternational Journal of Group Theory, 2023
If $\theta$ is a subgroup property, a group $G$ is said to satisfy the double chain condition on $\theta$-subgroups if it admits no infinite double chain ...

A survey on groups with some restrictions on normalizers or centralizers [PDF]

open access: yesInternational Journal of Group Theory, 2020
We consider conditions on normalizers or centralizers in a group and we collect results showing how such conditions influence the structure of the group.

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.

Torsion locally nilpotent groups with non-Dedekind norm of Abelian non-cyclic subgroups

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
The authors study relations between the properties of torsion locally nilpotent groups and their norms of Abelian non-cyclic subgroups. The impact of the norm of Abelian non-cyclic subgroups on the properties of the group under the condition of norm non ...

From Groups to Leibniz Algebras: Common Approaches, Parallel Results [PDF]

open access: yesAdvances in Group Theory and Applications, 2018
In this article, we study (locally) nilpotent and hyper-central Leibniz algebras. We obtained results similar to those in group theory. For instance, we proved a result analogous to the Hirsch-Plotkin Theorem for locally nilpotent groups.

4-ENGEL GROUPS ARE LOCALLY NILPOTENT [PDF]

open access: yesInternational Journal of Algebra and Computation, 2005
Questions about nilpotency of groups satisfying Engel conditions have been considered since 1936, when Zorn proved that finite Engel groups are nilpotent. We prove that 4-Engel groups are locally nilpotent. Our proof makes substantial use of both hand and machine calculations.

Compact groups with countable Engel sinks

open access: yesBulletin of Mathematical Sciences, 2021
An Engel sink of an element g of a group G is a set ℰ(g) such that for every x ∈ G all sufficiently long commutators [...[[x,g],g],…,g] belong to ℰ(g).

On groups with two isomorphism classes of central factors [PDF]

open access: yesInternational Journal of Group Theory, 2018
The structure of groups which have at most two isomorphism classes of central factors ($B_2$-groups) are investigated‎. ‎A complete description of $B_2$-groups is obtained in the locally finite case and in the nilpotent case‎.

Relationships between the Factors of the Central Series and the Nilpotent Residual in Some Infinite Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2017
We consider some natural relationships between the factors of the central series in groups. It was proved that if $G$ is a locally generalized radical group and $G/\zeta_k(G)$ has finite section $p$-rank $r$ (for some positive integer $k$), then $G ...

Locally pro-pcontraction groups are nilpotent [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2021
AbstractThe authors have shown previously that every locally pro-pcontraction group decomposes into the direct product of ap-adic analytic factor and a torsion factor. It has long been known thatp-adic analytic contraction groups are nilpotent. We show here that the torsion factor is nilpotent too, and hence that every locally pro-pcontraction group is
