Noncommutative Geometry: Fuzzy Spaces, the Groenewold-Moyal Plane
Symmetry, Integrability and Geometry: Methods and Applications, 2006 In this talk, we review the basics concepts of fuzzy physics and quantum field theory on the Groenewold-Moyal Plane as examples of noncommutative spaces in physics. We introduce the basic ideas, and discuss some important results in these fields.

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Study of Anisotropic Compact Star Model in Modified Gravity Using Finch–Skea Geometry
Advances in Astronomy, Volume 2024, Issue 1, 2024.In this work, we construct a new model of compact stars in the presence of anisotropic matter in the Rastall theory of gravity. For this, we considered the anisotropic matter content when formulating the Rastall field equations. Secondly, the Tolman–Oppenheimer–Volkoff (TOV) equation in the context of Rastall theory is formulated.

Beyond the Standard Model with noncommutative geometry, strolling towards quantum gravity
, 2015 Noncommutative geometry, in its many incarnations, appears at the crossroad of various researches in theoretical and mathematical physics: from models of quantum space-time (with or without breaking of Lorentz symmetry) to loop gravity and string theory,

Eigenvalues of Relatively Prime Graphs Connected with Finite Quasigroups
Journal of Mathematics, Volume 2024, Issue 1, 2024.A relatively new and rapidly expanding area of mathematics research is the study of graphs’ spectral properties. Spectral graph theory plays a very important role in understanding certifiable applications such as cryptography, combinatorial design, and coding theory.

On Consistency Of Noncommutative Chern-Simons Theory
, 2007 We consider the noncommutative extension of Chern-Simons theory. We show the the theory can be fully expanded in power series of the noncommutative parameter theta and that no non-analytical sector exists.

Research on Least‐Square η‐Hermitian Solutions of Split Quaternion Matrix Equations
Journal of Mathematics, Volume 2024, Issue 1, 2024.In this article, we use the real representation matrix of the split quaternion matrix, vector operator, Kronecker product, and Moore–Penrose generalized inverse. We establish the least norm expression of the least‐square η‐Hermitian solution and the least norm expression of the least‐square η‐anti‐Hermitian solution on the split quaternion of the ...

Quantum scalar field on fuzzy de Sitter space. Part I. Field modes and vacua
Journal of High Energy PhysicsWe study a scalar field on a noncommutative model of spacetime, the fuzzy de Sitter space, which is based on the algebra of the de Sitter group SO(1, d) and its unitary irreducible representations. We solve the Klein-Gordon equation in d = 2, 4 and show,

A New Matrix Model for Noncommutative Field Theory
, 2003 We describe a new regularization of quantum field theory on the noncommutative torus by means of one-dimensional matrix models. The construction is based on the Elliott-Evans inductive limit decomposition of the noncommutative torus algebra.
