16 Jul 2003 | | Journal: | Eur.Phys.J. C31 (2003) 129-138 | | Subject: | hep-th | | Abstract: | A general formalism is developed that allows the construction of a field theory on quantum spaces which are deformations of ordinary spacetime. The symmetry group of spacetime (Poincare group) is replaced by a quantum group. This formalism is demonstrated for the kappa-deformed Poincaré algebra and its quantum space. The algebraic setting is mapped to the algebra of functions of commuting variables with a suitable star-product. Fields are elements of this function algebra. The Dirac and Klein-Gordon equation are defined and an action is found from which they can be derived. | | Source: | arXiv, hep-th/0307149 | | Services: | Forum | Review | PDF | Favorites | |
