Primitive near-rings [PDF]

open access: yes, 1970
The theory of near-rings has arisen in a variety of ways. There is a natural desire to generalise the theory of rings and skew fields by relaxing some of their defining axioms.

XY* Transition and Extraordinary Boundary Criticality from Fractional Exciton Condensation in Quantum Hall Bilayer

open access: yesPhysical Review X, 2023
XY* transitions represent one of the simplest examples of unconventional quantum criticality, in which fractionally charged excitations condense into a superfluid and display novel features that combine quantum criticality and fractionalization ...

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 Riemann wave superpositions obtained from the Euler system [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics
The paper contains an analysis of the conditions for the existence of elastic versus non-elastic wave superpositions governed by the Euler system in (1+1)-dimensions.

Carrollian approach to 1 + 3D flat holography

open access: yesJournal of High Energy Physics, 2023
The isomorphism between the (extended) BMS4 algebra and the 1 + 2D Carrollian conformal algebra hints towards a co-dimension one formalism of flat holography with the field theory residing on the null-boundary of the asymptotically flat space-time ...

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 ...

Ideal-determined categories [PDF]

open access: yes, 2010
The authors clarify the role of Hofmann's Axiom in the old-style definition of a semi-abelian category. By removing this axiom they obtain the categorical counterpart of the notion of an ideal determined variety of universal algebras - which they ...

On the Cyclotomic Unit Group and the Ideal Class Group of a Real Abelian Number Field

open access: yes, 1997
LetKbe a real abelian number field satisfying certain conditions andKnthenth layer of the cyclotomic Zp-extension ofK. We study the relations between thep-Sylow subgroup of the ideal class group and that of the unit group modulo the cyclotomic unit group

Blaschke inductive limits of uniform algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider and study Blaschke inductive limit algebrasA(b), defined as inductive limits of disc algebras A(D) linked by a sequence b={Bk}k=1∞ of finite Blaschke products.
