Compactifications of strata of differentials

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3621-3636, December 2025.
Abstract In this informal expository note, we quickly introduce and survey compactifications of strata of holomorphic 1‐forms on Riemann surfaces, that is, spaces of translation surfaces. In the last decade, several of these have been constructed, studied, and successfully applied to problems.

Automorphisms of Cayley graphs on generalised dicyclic groups

open access: yes, 2013
A graph is called a GRR if its automorphism group acts regularly on its vertex-set. Such a graph is necessarily a Cayley graph. Godsil has shown that there are only two infinite families of finite groups that do not admit GRRs : abelian groups and ...

A categorical interpretation of continuous orbit equivalence for partial dynamical systems

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3637-3656, December 2025.
Abstract We define the orbit morphism of partial dynamical systems and prove that an orbit morphism being an isomorphism in the category of partial dynamical systems and orbit morphisms is equivalent to the existence of a continuous orbit equivalence between the given partial dynamical systems that preserves the essential stabilisers. We show that this

Geometric dynamics on the automorphism group of principal bundles: geodesic flows, dual pairs and chromomorphism groups

open access: yes, 2010
We formulate Euler-Poincar\'e equations on the Lie group Aut(P) of automorphisms of a principal bundle P. The corresponding flows are referred to as EPAut flows. We mainly focus on geodesic flows associated to Lagrangians of Kaluza-Klein type.

Some infinite soluble groups, their modules, and the arithmeticity of associated automorphism groups

open access: yesJournal of Algebra, 2005
In recent years the authors have made detail studies of modules over a crossed product of a division ring by an Abelian group, promising us that there were group theoretic applications to come. In this current paper we get these applications, or at least some of them. There are three. The first concerns a module \(M\) over the group ring \(RG\), where \

Automorphism Groups of Configuration Spaces and Discriminant Varieties

open access: yes, 2015
The configuration space $\mathcal{C}^n(X)$ of an algebraic curve $X$ is the algebraic variety consisting of all $n$-point subsets $Q\subset X$. We describe the automorphisms of $\mathcal{C}^n(\mathbb{C})$, deduce that the (infinite dimensional) group Aut$
