Hopf-Algebra Description of Noncommutative-Spacetime Symmetries

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

A brief summary is given of the results reported in [hep-th/0306013], in collaboration with G. Amelino-Camelia and F. D'Andrea. It is focused on the analysis of the symmetries of κ-Minkowski noncommutative spacetime, described in terms of a Weyl map. The commutative-spacetime notion of Lie-algebra symmetries must be replaced by the one of Hopf-algebra symmetries. However, in the Hopf-algebra sense, it is possible to construct an action in κ-Minkowski, which is invariant under a 10-generators Poincaré-like symmetry algebra.
