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.

Radical preservation and the finitistic dimension

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We introduce the notion of radical preservation and prove that a radical‐preserving homomorphism of left artinian rings of finite projective dimension with superfluous kernel reflects the finiteness of the little finitistic, big finitistic, and global dimension.

Quiver theories and formulae for nilpotent orbits of Exceptional algebras

open access: yesJournal of High Energy Physics, 2017
We treat the topic of the closures of the nilpotent orbits of the Lie algebras of Exceptional groups through their descriptions as moduli spaces, in terms of Hilbert series and the highest weight generating functions for their representation content.

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Finite semigroups that are minimal for not being Malcev nilpotent

open access: yes, 2014
We give a description of finite semigroups $S$ that are minimal for not being Malcev nilpotent, i.e. every proper subsemigroup and every proper Rees factor semigroup is Malcev nilpotent but $S$ is not.

Nilpotent groups and their generalizations [PDF]

open access: yesTransactions of the American Mathematical Society, 1940
Nilpotent finite groups may be defined by a great number of properties. Of these the following three may be mentioned, since they will play an important part in this investigation. (1) The group is swept out by its ascending central chain (equals its hypercentral). (2) The group is a direct product of p-groups (that is, of its primary components).

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Commutators and Squares in Free Nilpotent Groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
In a free group no nontrivial commutator is a square. And in the free group F2=F(x1,x2) freely generated by x1,x2 the commutator [x1,x2] is never the product of two squares in F2, although it is always the product of three squares.

(c,1,...,1) Polynilpotent Multiplier of some Nilpotent Products of Groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
In this paper we determine the structure of (c,1,...,1) polynilpotent multiplier of certain class of groups. The method is based on the characterizing an explicit structure for the Baer invariant of a free nilpotent group with respect to the variety of ...

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.
