Lie algebras: infinite generalizations and deformations [PDF]
, 1990 There are many applications of Lie algebras to theoretical physics. This thesis is a study of some new mathematical structures which also are applicable to current physical ideas.

The Weyl-Wigner-Moyal formalism for spin
, 2013 The Weyl-Wigner-Moyal formalism is developed for spin by means of a correspondence between spherical harmonics and spherical-harmonic tensor operators. The exact asymptotic relation among the P, Q, and Weyl symbols is found, and the analogue of the Moyal

Searching for Universality of Turbulence in the Earth's Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract Turbulence in space plasmas remains a fundamental challenge, and Earth's magnetosphere (MSP) offers a natural laboratory for its study. Using high‐resolution magnetic field data from the Magnetospheric Multiscale (MMS) mission, we extend a stochastic Markovian framework to analyze turbulence across 10 diverse magnetospheric regions, including ...

, 2016 We construct a family of constant curvature metrics on the Moyal plane and compute the Gauss–Bonnet term for each of them. They arise from the conformal rescaling of the metric in the orthonormal frame approach.

Family resemblance and the problem of universals: Bambrough's analysis revisited
Philosophical Investigations, Volume 48, Issue 4, Page 401-420, October 2025.Abstract In ‘Universals and Family Resemblances’, Renford Bambrough claims that Ludwig Wittgenstein's conception of family resemblance solves the problem of universals. Bambrough's analysis has attracted a number of criticisms, including (i) that his exposition of the problem of universals is ill‐conceived, (ii) that he overgeneralizes Wittgenstein's ...

The Moyal Product and Spectral Theory for a Class of Infinite Dimensional Matrices
Publications of the Research Institute for Mathematical Sciences, 1990 We study tempered distributions that are multipliers of the Schwartz space relative to the Moyal product. They form an algebra N under the Moyal product containing the polynomials. The elements of N are represented as infinite dimensional matrices with ...

The ultraviolet infrared mixing problem on the noncommutative Moyal space
, 2010 It is shown that the mixing of ultraviolet and infrared divergences in quantum field theory on Moyal space is not an artefact of the Euclidean framework, but occurs also in the Hamiltonian setting when the interaction is given in terms of the Moyal ...

Asymptotic Behaviour of Determinants Through the Expansion of the Moyal Star Product
Communications in Mathematical PhysicsWe work out a generalization of the Szegö limit theorems on the determinant of large matrices. We focus on matrices with nonzero leading principal minors and elements that decay to zero exponentially fast with the distance from the main diagonal, but we relax the constraint of the Toeplitz structure. We obtain an expression for the asymptotic behaviour

, 2022 A full consideration of classical and quantum systems with radiation (electromagnetic/gravitational) requires the involvement of a mathematical description in the generalized phase space of high kinematical values.
