Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Context‐free graphs and their transition groups
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

Integration In Abelian $C^*$-Dynamical Systems
Publications of the Research Institute for Mathematical Sciences, 1985 Let \({\mathcal A}=C_ 0(x)\) be an abelian \(C^*\)-algebra, and let \(\delta_ 0\) be the generator of a strongly continuous group of *- automorphisms on \({\mathcal A}\). Derivations of the form \(\delta =\lambda \delta_ 0\) are considered, where \(\lambda\) is a multiplication operator on \(C_ 0(x)\).

Pseudo-Abelian integrals along Darboux cycles: A codimension one case [PDF]
, 2009 We investigate a polynomial perturbation of an integrable, non-Hamiltonian system with first integral of Darboux type. In the paper [M. Bobieński, P. Mardešić, Pseudo-Abelian integrals along Darboux cycles, Proc. Lond. Math.

Geometry of soft scalars at one loop
Journal of High Energy PhysicsWe extend the soft theorems for scattering amplitudes of scalar effective field theories to one-loop order. Our analysis requires carefully accounting for the fact that the soft limit is not guaranteed to commute with evaluating IR-divergent loop ...

Abelian number fields with frobenian conditions
Mathematika, Volume 72, Issue 4, October 2026.Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

Non‐Hermitian Stealthy Hyperuniformity
Advanced Science, Volume 13, Issue 49, 3 September 2026.A framework for non‐Hermitian extensions of hyperuniformity and stealthiness is proposed, generalizing PT‐symmetric gain‐loss crystals to correlated disorder in the weak‐scattering limit. By engineering real‐imaginary correlations of the material potential, this framework enables directional scattering phases inaccessible in Hermitian materials ...

Constructions of complex hadamard matrices via tiling abelian groups [PDF]
, 2007 Applications in quantum information theory and quantum tomography have raised current interest in complex Hadamard matrices. In this note we investigate the connection between tiling of Abelian groups and constructions of complex Hadamard matrices ...

The continuity of the gauge fixing condition n⋅∂n⋅A=0
Nuclear Physics B, 2018 To investigate the continuity of the gauge condition n⋅∂n⋅A=0, the continuity of generators of Wilson lines is studied here in the frame of non-Abelian gauge theory in the space R⨂S1⨂S1⨂S1, which guarantees the continuity of the gauge condition n⋅∂n⋅A=0 ...
