Index Theorem in Finite Noncommutative Geometry

, 2007
Index theorem is formulated in noncommutative geometry with finite degrees of freedom by using Ginsparg-Wilson relation. It is extended to the case where the gauge symmetry is spontaneously broken.

From Noncommutative Sphere to Nonrelativistic Spin

Symmetry, Integrability and Geometry: Methods and Applications, 2010
Reparametrization invariant dynamics on a sphere, being parameterized by angular momentum coordinates, represents an example of noncommutative theory.

Seesaw and noncommutative geometry

, 2007
The 1-loop corrections to the seesaw mechanism in the noncommutative standard model are computed. Other consequences of the Lorentzian signature in the inner space are summarised.Comment: Dedicated to Alain Connes on the occasion of his 60th ...

Metric perturbations in noncommutative gravity

Journal of High Energy Physics
We use the framework of Hopf algebra and noncommutative differential geometry to build a noncommutative (NC) theory of gravity in a bottom-up approach.

Time-dependent Aharonov–Bohm effect on the noncommutative space

Physics Letters B, 2016
We study the time-dependent Aharonov–Bohm effect on the noncommutative space. Because there is no net Aharonov–Bohm phase shift in the time-dependent case on the commutative space, therefore, a tiny deviation from zero indicates new physics. Based on the

WKB Approximation in Noncommutative Gravity

Symmetry, Integrability and Geometry: Methods and Applications, 2007
We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency ...

Macroscopic wormholes in noncommutative geometry

, 2013
The purpose of this paper is to show that wormholes in noncommutative geometry can be macroscopic, based in part on an earlier study. The necessary violation of the weak energy condition is attributable to the noncommutative-geometry background rather ...

On tea, donuts and non-commutative geometry [PDF]

Surveys in Mathematics and its Applications, 2018
As many will agree, it feels good to complement a cup of tea by a donut or two. This sweet relationship is also a guiding principle of non-commutative geometry known as Serre Theorem.
