Gravity and Electromagnetism in Noncommutative Geometry
We present a unified description of gravity and electromagnetism in the framework of a Z2 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. We derive an action which coincides with the dimensionally reduced one of the ordinary Kaluza-Klein theory. PACS. 04.20.Jb, 04....
متن کاملCoframe geometry, gravity and electromagnetism
The extensions of GR for description of fermions on a curved space, for supergravity, and for the loop quantum gravity ordinary use a set of 16 independent variables instead of 10 components of metric. These variables can be assembled in a coframe field, i.e., a set of four linearly independent 1-forms. In this presentation we review a geometrical structure based on the coframe field. We constr...
متن کاملGravity From Noncommutative Geometry
We introduce the linear connection in the noncommutative geometry model of the product of continuous manifold and the discrete space of two points. We discuss its metric properties, de ne the metric connection and calculate the curvature. We de ne also the Ricci tensor and the scalar curvature. We nd that the latter di ers from the standard scalar curvature of the manifold by a term, which migh...
متن کاملHamiltonian Gravity and Noncommutative Geometry
A version of foliated spacetime is constructed in which the spatial geometry is described as a time dependent noncommutative geometry. The ADM version of the gravitational action is expressed in terms of these variables. It is shown that the vector constraint is obtained without the need for an extraneous shift vector in the action.
متن کاملIntersecting Connes Noncommutative Geometry with Quantum Gravity
An intersection of Noncommutative Geometry and Loop Quantum Gravity is proposed. Alain Connes’ Noncommutative Geometry provides a framework in which the Standard Model of particle physics coupled to general relativity is formulated as a unified, gravitational theory. However, to this day no quantization procedure compatible with this framework is known. In this paper we consider the noncommutat...
