Quasi-Dirac Operators on the Sphere
نویسنده
چکیده
We investigate examples of quasi-spectral triples over two-dimensional commutative sphere, which are obtained by modifying the order-one condition. We find quasi-Dirac operators and calculate the index paring with a representant of K-theory class to prove that the quasispectral triples are mutually inequivalent. MSC 2000: 58B34, 46L87, 34L40

Quasi-Dirac Operators and Quasi-Fermions
We investigate examples of quasi-spectral triples over two-dimensional commutative sphere, which are obtained by modifying the order-one condition. We find equivariant quasi-Dirac operators and prove that they are in a topologically distinct sector than the standard Dirac operator. MSC 2000: 58B34, 46L87, 34L40
متن کاملSome Sharp L Inequalities for Dirac Type Operators
We use the spectra of Dirac type operators on the sphere S to produce sharp L inequalities on the sphere. These operators include the Dirac operator on S, the conformal Laplacian and Paenitz operator. We use the Cayley transform, or stereographic projection, to obtain similar inequalities for powers of the Dirac operator and their inverses in R.
متن کاملLattice calculations on the spectrum of Dirac and Dirac - Kähler operators
We present a matrix technique to obtain the spectrum and the analytical index of some elliptic operators defined on compact Riemannian manifolds. The method uses matrix representations of the derivative which yield exact values for the derivative of a trigono-metric polynomial. These matrices can be used to find the exact spectrum of an elliptic operator in particular cases and in general, to g...

We construct new families of spectral triples over quantum spheres, with a particular attention focused on the standard Podleś quantum sphere and twisted Dirac operators.

The main thrust of this paper is to investigate the intimate link between the conformal group and singular integral operators, in particular, but not exclusively, operators of Calderón–Zygmund type, together with associated commutators acting on the L spaces of surfaces. Clifford analysis and Dirac operators are the basic tools used to help to unify these themes. These surfaces lie in euclidean...
