Differential forms and k-Minkowski spacetime from extended twist    [PDF]

Tajron Jurić, Stjepan Meljanac, Rina Štrajn

We unify k-Minkowski spacetime, k-Poincar\'e algebra and differential forms. We embed them into k-deformed super-Heisenberg algebra related to bicrossproduct basis. Using twist, extended with Grassmann type variables, we obtain extended realization for k-deformed coordinates, Lorentz generators and exterior derivative compatible with the symmetry algebra. Our results are relevant for constructing physical theories on noncommutative spacetime.
