On invariant ideals in group rings of torsion-free minimax nilpotent groups

open access: yesResearches in Mathematics, 2023
Let $k$ be a field and let $N$ be a nilpotent minimax torsion-free group acted by a solvable group of operators $G$ of finite rank. In the presented paper we study properties of some types of $G$-invariant ideals of the group ring $kN$.

Nilpotence in group cohomology [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2012
AbstractWe study bounds on nilpotence in H*(BG), the mod p cohomology of the classifying space of a compact Lie group G. Part of this is a report of our previous work on this problem, updated to reflect the consequences of Peter Symonds's recent verification of Dave Benson's Regularity Conjecture.

The first two group theory papers of Philip Hall

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract In this paper, we discuss the first two papers on soluble groups written by Philip Hall and their influence on the study of finite groups. The papers appeared in 1928 and 1937 in the Journal of the London Mathematical Society.

Locally finite p-groups with all subgroups either subnormal or nilpotent-by-Chernikov [PDF]

open access: yesInternational Journal of Group Theory, 2012
We pursue further our investigation, begun in [H.~Smith, Groups with all subgroups subnormal or nilpotent-by-{C}hernikov, emph{Rend. Sem. Mat. Univ. Padova} 126 (2011), 245--253] and continued in [G.~Cutolo and H.~Smith, Locally finite groups with all ...

Congruences associated with families of nilpotent subgroups and a theorem of Hirsch

open access: yesComptes Rendus. Mathématique, 2023
Our main result associates a family of congruences with each suitable system of nilpotent subgroups of a finite group. Using this result, we complete and correct the proof of a theorem of Hirsch concerning the class number of a finite group of odd order.

On Finite Nilpotent Groups [PDF]

open access: yesCanadian Journal of Mathematics, 1960
It is well known that if (n, ϕ(n)) = 1, where ϕ(n) denotes the Euler ϕ function, then the only group of order n is the cyclic group. This is a special case of a more general result due to Dickson (2, p. 201); namely, ifwhere the pi are distinct primes and each αi > 0, the necessary and sufficient conditions that the only groups of order n are ...

Homotopy nilpotent groups [PDF]

open access: yesAlgebraic & Geometric Topology, 2010
We study the connection between the Goodwillie tower of the identity and the lower central series of the loop group on connected spaces. We define the simplicial theory of homotopy n-nilpotent groups. This notion interpolates between infinite loop spaces and loop spaces.

Random planar trees and the Jacobian conjecture

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We develop a probabilistic approach to the celebrated Jacobian conjecture, which states that any Keller map (i.e. any polynomial mapping F:Cn→Cn$F\colon \mathbb {C}^n \rightarrow \mathbb {C}^n$ whose Jacobian determinant is a non‐zero constant) has a compositional inverse which is also a polynomial. The Jacobian conjecture may be formulated in
