On the Lang–Trotter conjecture for Siegel modular forms

open access: yesMathematika, Volume 72, Issue 3, July 2026.
Abstract Let f$f$ be a genus‐two cuspidal Siegel eigenform. We prove an adelic open image theorem for the compatible system of Galois representations associated with f$f$, generalizing the results of Ribet and Momose for elliptic modular forms. Using this result, we investigate the distribution of the Hecke eigenvalues ap$a_p$ of f$f$, and obtain upper

On extensions of bounded subgroups in Abelian groups [PDF]

open access: yes, 2014
summary:It is well-known that every bounded Abelian group is a direct sum of finite cyclic subgroups. We characterize those non-trivial bounded subgroups $H$ of an infinite Abelian group $G$, for which there is an infinite subgroup $G_0$ of $G ...

On Abelian Subgroups ofp-Groups

open access: yesJournal of Algebra, 1998
Let \(p\) be a prime and let \(G\) be a finite \(p\)-group. Abelian subgroups of the group \(G\) are investigated here. The author generalizes and presents simplified proofs of almost all elementary lemmas from Section 8 of the odd order paper. In particular it is proved, that if \(A2\), and \(\mathcal U\) is the set of all abelian subgroups \(T\) of \(

On the Meaning of Localization in Non‐Local Quantum Field Theory

open access: yesAnnalen der Physik, Volume 538, Issue 6, June 2026.
In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Fuzzy Internal Direct Product

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2019
The purpose of this research is to show a constructive method for using known fuzzy groups as building blocks to form more fuzzy subgroups. As we shall describe employing this procedure with the fuzzy generating subgroups give us a large class of ...

Cyclic subgroup transitivity for Abelian groups

open access: yesRendiconti del Seminario Matematico della Università di Padova, 2023
In previous work, the first two authors studied the notion of transitivity with respect to cyclic subgroups for separable Abelian p -groups and modules over the ring of p

Placebo in Paediatric Clinical Trials: Systematic Literature Review and Framework‐Based Synthesis

open access: yesJournal of Paediatrics and Child Health, Volume 62, Issue 6, Page 916-923, June 2026.
ABSTRACT Introduction Placebo‐controlled trials can provide strong evidence on safety and efficacy, but their ethical acceptability in paediatric research is contested because children have limited decisional capacity and placebo use may entail withholding effective therapy.

The singularity category and duality for complete intersection groups

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract If G$G$ is a finite group, the structure of the modular representation theory depends on the cochains C∗(BG;k)$C^*(BG; k)$, viewed as a commutative ring spectrum. We consider here its singularity category (in the sense of the author and Stevenson [Adv. Math.

A characterization of metaplectic time–frequency representations

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We characterize all time–frequency representations that satisfy a general covariance property: any weak*‐continuous bilinear mapping that intertwines time–frequency shifts on the configuration space with time–frequency shifts on phase space is a multiple of a metaplectic time–frequency representation. This characterization offers an intrinsic,

On the cohomology of finite‐dimensional nilpotent groups and Lie rings

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We establish vanishing results for the first cohomology group of nilpotent groups and Lie rings when the submodule of invariants is trivial. Our results are obtained within a model‐theoretic setting, namely for structures that are definable in a finite‐dimensional theory, which encompasses algebraic groups over algebraically closed fields ...
