A question of Bukh on sums of dilates

open access: yesDiscrete Analysis, 2021
A question of Bukh on sums of dilates, Discrete Analysis 2021:13, 21 pp. Let $A$ and $B$ be subsets of an Abelian group. Their sumset $A+B$ is defined to be the set of all $a+b$ such that $a\in A$ and $b\in B$.

Isometric immersions into three‐dimensional unimodular metric Lie groups

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.

The landscape of composite Higgs models

open access: yesJournal of High Energy Physics
We classify all different composite Higgs models (CHMs) characterised by the coset space G $$ \mathcal{G} $$ / H $$ \mathcal{H} $$ of compact semi-simple Lie groups G $$ \mathcal{G} $$ and H $$ \mathcal{H} $$ involving up to 13 Nambu-Goldstone bosons ...

Multiplicative irreducibility of shifted multiplicative subgroups

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract In a recent breakthrough, Kalmynin resolved conjectures of Lev–Sonn and Sárközy on additive decompositions of multiplicative subgroups of prime fields. In this paper, inspired by a related conjecture of Sárközy, we prove multiplicative analogues of Kalmynin's results. We show that for every proper multiplicative subgroup G$G$, the shifted set (

Extending the analysis of electroweak precision constraints in composite Higgs models

open access: yesNuclear Physics B, 2017
In this paper we present a detailed analysis of the Electroweak Precision Observables (EWPO) in composite Higgs models based on the coset SO(5)/SO(4). In our study we include both the fermionic top partners and the spin-1 resonances and consider their ...

Equidistribution in 2‐nilpotent Polish groups and triple restricted sumsets

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract The aim of this paper is to establish a Ratner‐type equidistribution theorem for orbits on homogeneous spaces associated with 2$\hskip.001pt 2$‐nilpotent locally compact Polish groups under the action of a countable discrete abelian group.

Implications of Coding Layers on Physical-Layer Security: A Secrecy Benefit Approach

open access: yesEntropy, 2019
In this work, we consider the pros and cons of using various layers of keyless coding to achieve secure and reliable communication over the Gaussian wiretap channel. We define a new approach to information theoretic security, called practical secrecy and

Sidon sets from Erdős and Turán to yesterday

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Motivated by some problems in Fourier analysis, Sidon asked for the maximum number of integers in a block of given length with the property that their pairwise sums are all distinct. The first estimate is due to P. Erdős and P. Turán [J. Lond. Math. Soc. (1) 16 (1941), 212–215].
