Query: Hopf-algebra description of noncommutative-spacetime symmetries   I give a brief summary of the results reported in hep-th 0306013 in
collaboration with G. Amelino-Camelia and F. D'Andrea. I focus on the analysis
of the symmetries of $\kappa$-Minkowski noncommutative space-time, described in
terms of a Weyl map. The commutative space-time 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
$\kappa$-Minkowski which is invariant under a 10-generators Poincar\'e-like
symmetry algebra.
