A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Physical constraints on quantum deformations of spacetime symmetries
Nuclear Physics B, 2018 In this work we study the deformations into Lie bialgebras of the three relativistic Lie algebras: de Sitter, Anti-de Sitter and Poincaré, which describe the symmetries of the three maximally symmetric spacetimes. These algebras represent the centerpiece

Fractional Nikiforov‐Uvarov Formalism for Dunkl‐Schrödinger Equation With Deng‐Fan Molecular Model
International Journal of Quantum Chemistry, Volume 126, Issue 19, October 5, 2026.The effect of Dunkl deformation parameters on energy eigenvalues of Deng‐Fan potential (DFP) is evaluated using conformable fractional Nikiforov‐Uvarov method. Our results show that energy eigenvalues of DFP for selected diatomic molecules are significantly influenced by the Dunkl deformation parameter, fractional parameter, kinetic pre‐factor and ...

Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT We construct Lax pairs for the recently (2023) introduced integrable PDE systems known as the BKM equations. As many known and previously studied integrable systems are special cases of the BKM systems, our construction provides Lax pairs for many integrable hierarchies, including previously studied ones such as Camassa–Holm, Dullin–Gottwald ...

When weak convergence in von Neumann algebras implies almost uniform convergence?
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract We show that weak sequential convergence in a semifinite von Neumann algebra M$\mathcal {M}$ equipped with a faithful normal semifinite trace τ$\tau$ implies almost uniform convergence if and only if M$\mathcal {M}$ is of type Ifin$\mathrm{I}_{\rm fin}$ with τ(1)<∞;$\tau (\mathbf {1})<\infty;$ and that weak sequential convergence in a finite ...

Geometry of essential matrix ranges and the Smith–Ward problem for operator systems
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract A d$d$‐tuple of bounded linear selfadjoint operators acting on an infinite‐dimensional separable Hilbert space is said to have the Smith–Ward property if the identity map of the image of the operator system in the Calkin algebra has a completely positive lift.

Type C$C$ skein modules and transparent elements
Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.Abstract We study skein modules using Sp(2n)$\textit{Sp}(2n)$ webs. We define multivariable analogues of Chebyshev polynomials in the Type C$C$ setting and use them to construct transparent elements in the skein module at roots of unity. Our arguments are diagrammatic and make use of an explicit braiding formula for 1 and k$k$ labeled strands and an ...

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics
Natural Sciences, Volume 6, Issue 3, July 2026.ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

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