First results of the Noether theorem for Hopf-algebra spacetime symmetries

Abstract

We summarize here the first results obtained using a technique we recently developed for the Noether analysis of Hopf-algebra spacetime symmetries, including the derivation of conserved charges for field theories in noncommutative spacetimes of canonical or kappa-Minkowski type.
