Commutators in Rings

Irish Mathematical Society Bulletin, 1996
Summary: We exhibit with proof a ring of minimal order in which the commutator subset is not a subring.

On Nielsen equivalence classes of two‐element generators of mapping class groups

Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract We show that there are infinitely many Nielsen equivalence classes of the mapping class group of a closed oriented surface of genus at least eight.

A graph-theoretic approach to chaos and complexity in quantum systems

SciPost Physics Core
There has recently been considerable interest in studying quantum systems via dynamical Lie algebras (DLAs) – Lie algebras generated by the terms which appear in the Hamiltonian of the system.

Totally elliptic surface group representations

Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract A surface group representation into a Lie group is totally elliptic if every simple closed curve on the surface is mapped to an elliptic element. In this note, we characterize all totally elliptic surface group representations into PSL2R$\operatorname{PSL}_2 \mathbb {R}$ and PSL2C$\operatorname{PSL}_2\mathbb {C}$ by showing that they are ...

A birational description of the minimal exponent

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We give a description of the minimal exponent of a hypersurface using higher direct images of suitably twisted sheaves of log forms on a log resolution.

Derivations as algebras

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract Differential categories provide the categorical foundations for the algebraic approaches to differentiation. They have been successful in formalizing various important concepts related to differentiation, such as, in particular, derivations. In this paper, we show that the differential modality of a differential category lifts to a monad on ...

Heights on ‘hybrid orbits’ in Shimura varieties

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We prove the ‘hybrid conjecture’ which is a common generalisation of the André–Oort conjecture and the André–Pink–Zannier conjecture, in the case of Shimura varieties of abelian type.

A note on transfer theorems [PDF]

International Journal of Group Theory, 2016
In this paper, we generalize some transfer theorems.~In particular, we derive one of the main results of Gagola(Contemp Math 524:49--60, 2010) from our results.
