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