Field Equations and Radial Solutions in a Noncommutative Spherically Symmetric Geometry

open access: yesAdvances in High Energy Physics, 2014
We study a noncommutative theory of gravity in the framework of torsional spacetime. This theory is based on a Lagrangian obtained by applying the technique of dimensional reduction of noncommutative gauge theory and that the yielded diffeomorphism ...

Generalised noncommutative geometry on finite groups and Hopf quivers [PDF]

open access: yesJournal of Noncommutative Geometry, 2016
We explore the differential geometry of finite sets where the differential structure is given by a quiver rather than as more usual by a graph. In the finite group case we show that the data for such a differential calculus is described by certain Hopf ...

A Geometric Approach to Noncommutative Principal Torus Bundles

open access: yes, 2012
A (smooth) dynamical system with transformation group $\mathbb{T}^n$ is a triple $(A,\mathbb{T}^n,\alpha)$, consisting of a unital locally convex algebra $A$, the $n$-torus $\mathbb{T}^n$ and a group homomorphism $\alpha:\mathbb{T}^n\rightarrow\Aut(A ...

A Unified Approach to Image Recognition and Cryptography via Flexible Weak Inverse Property Quasigroups

open access: yesJournal of Function Spaces, Volume 2025, Issue 1, 2025.
Nonassociative algebra presents multiple options for comprehending and dealing with difficulties in graph theory, artificial intelligence, and cryptography. Its distinctive traits introduce genuine concepts and procedures not found in conventional associative algebra, yielding to new results from studies and breakthroughs in multiple disciplines ...

Geometry of noncommutative algebras [PDF]

open access: yesBanach Center Publications, 2011
Let X be a scheme over an algebraically closed field k, and let x ∈ SpecR ⊆ X be a closed point corresponding to the maximal ideal m ⊆ R. Then OˆX,x is isomorphic to the prorepresenting hull, or local formal moduli, of the deformation functor DefR/m : → Sets. This suffices to reconstruct X up to etal´e coverings.

Some special types of determinants in graded skew P BW extensions.

open access: yesRevista Integración, 2021
In this paper, we prove that the Nakayama automorphism of a graded skew PBW extension over a finitely presented Koszul Auslanderregular algebra has trivial homological determinant.

Significantly super-Chandrasekhar mass-limit of white dwarfs in noncommutative geometry

open access: yes, 2019
Chandrasekhar made the startling discovery about nine decades back that the mass of compact object white dwarf has a limiting value, once nuclear fusion reactions stop therein.

Various Properties of the Quasi‐Regular Graphs Over the Rings Zn

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
Zeyada, Muthana, and Al Rashidi recently introduced and investigated a quasi‐regular graph of rings. In this paper, we shall examine various aspects of this idea, with particular attention to the finite ring Zn. More precisely, we calculate the independent and domination numbers of QZn.

Gravity and electromagnetism in noncommutative geometry [PDF]

open access: yesPhysics Letters B, 1994
We present a unified description of gravity and electromagnetism in the framework of a $Z_2$ noncommutative differential calculus. It can be considered as a ``discrete version" of Kaluza-Klein theory, where the fifth continuous dimension is replaced by two discrete points.

Crystals, instantons and quantum toric geometry

open access: yes, 2011
We describe the statistical mechanics of a melting crystal in three dimensions and its relation to a diverse range of models arising in combinatorics, algebraic geometry, integrable systems, low-dimensional gauge theories, topological string theory and ...
