Kappa-Minkowski differential calculi and star product
arXiv:1105.1599 · doi:10.22323/1.127.0030
Abstract
We present the star-product algebra of the kappa-deformation of Minkowski space and the formulation of Poincare covariant differential calculus. We use these tools to construct a twisted K-cycle over the algebra and a twisted cyclic cocycle.
