Groups whose Proper Subgroups of Infinite Rank are Minimax-by-Nilpotent or Nilpotent-by-Minimax [PDF]

open access: yesAdvances in Group Theory and Applications, 2020
Let M denote the class of of soluble-by-finite minimax groups, and N the class of nilpotent groups. The main result states that if G is a group of infinite rank whose proper subgroups of infinite rank are MN-groups, then G is either in MN or it is a ...

On groups covered by locally nilpotent subgroups [PDF]

open access: yes, 2016
Let N be the class of pronilpotent groups, or the class of locally nilpotent profinite groups, or the class of strongly locally nilpotent profinite groups. It is proved that a profinite group G is finite-by-N if and only if G is covered by countably many

Fitting quotients of finitely presented abelian-by-nilpotent groups [PDF]

open access: yes, 2013
We show that every finitely generated nilpotent group of class 2 occurs as the quotient of a finitely presented abelian-by-nilpotent group by its largest nilpotent normal subgroup.Comment: This second version takes into account the suggestions by the ...

Pseudocomplete nilpotent groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
Semicomplete nilpotent groups, that is, nilpotent groups with no outer automorphisms, have been of interest for many years. In this paper pseudocomplete nilpotent groups, that is, nilpotent groups in which the automorphism group and the inner automorphism group are isomorphic (not equal), are constructed.

On the permutability of Sylow subgroups with derived subgroups of B-subgroups

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
A finite non-nilpotent group G is called a B-group if every proper subgroup of the quotient group  G/Φ(G) is nilpotent. We establish the r-solvability of the group in which some Sylow r-subgroup permutes with the derived subgroups of 2-nilpotent (or 2 ...

Recognising nilpotent groups

open access: yesJournal of Algebra, 2006
Let \(G\) be a finite group and order the set of sizes of conjugacy classes of \(G\) decreasingly to obtain what is called the conjugate type vector of \(G\). The authors show by examples that if \(H\) is nilpotent and if \(G\) and \(H\) have the same conjugate type vector, then \(G\) is not necessarily nilpotent.

The nilpotent ( p-group) of (D25 X C2n) for m > 5 [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2023
Every finite p-group is nilpotent. The nilpotence property is an hereditary one. Thus, every finite p-group possesses certain remarkable characteristics.

The solvability of groups with nilpotent minimal coverings [PDF]

open access: yes, 2014
A covering of a group is a finite set of proper subgroups whose union is the whole group. A covering is minimal if there is no covering of smaller cardinality, and it is nilpotent if all its members are nilpotent subgroups. We complete a proof that every

On almost finitely generated nilpotent groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
A nilpotent group G is fgp if Gp, is finitely generated (fg) as a p-local group for all primes p; it is fg-like if there exists a nilpotent fg group H such that Gp≃Hp for all primes p.

On some groups whose subnormal subgroups are contranormal-free [PDF]

open access: yesInternational Journal of Group Theory
If $G$ is a group, a subgroup $H$ of $G$ is said to be contranormal in $G$ if $H^G = G$, where $H^G$ is the normal closure of $H$ in $G$. We say that a group is contranormal-free if it does not contain proper contranormal subgroups.
