Gravity 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 کاملInflationary Cosmology from Noncommutative Geometry
In the framework of the Connes-Lott model based on noncommutative geometry, the basic features of a gauge theory in the presence of gravity are reviewed, in order to show the possible physical relevance of this scheme for inflationary cosmology. These models naturally contain at least two scalar fields, interacting with each other whenever more than one fermion generation is assumed. In this pa...
متن کاملCP - violation from Noncommutative Geometry ∗
If the geometry of space-time is noncommutative, i.e. [x µ , x ν ] = iθ µν , then noncommutative CP violating effects may be manifest at low energies. For a noncommutative scale Λ ≡ θ −1/2 ≤ 2 T eV , CP violation from noncommutative geometry is comparable to that from the Standard Model (SM) alone: the noncommutative contributions to ǫ and ǫ ′ /ǫ in the K-system, and to sin 2β in the B-system, ...
متن کاملSupersymmetric Noncommutative Solitons 1
I consider a supersymmetric Bogomolny-type model in 2+1 dimensions originating from topological string theory. By a gauge fixing this model is reduced to a supersymmetric U(n) chiral model with aWess-Zumino-Witten-type term in 2+1 dimensions. After a noncommutative extension of the model, I employ the dressing method to construct explicit multi-soliton configurations on noncommutative R .

We study the noncommutative geometry of a two-leaf Parisi{Sourlas supermanifold in Connes' formalism using di erent K-cycles over the Grassmann algebra valued functions on the supermanifold. We nd that the curvature of the trivial noncommutative vector bundle de nes in the simplest case the super Yang{Mills action coupled to a scalar eld. By considering a modi ed Dirac operator and a suitable l...
