Query: Symplectic geometry and Noether charges for Hopf algebra space-time
  symmetries   There has been a certain interest in some recent works in the derivation of
Noether charges for Hopf-algebra space-time symmetries. Such analyses relied
rather heavily on delicate manipulations of the fields of non-commuting
coordinates whose charges were under study. Here we derive the same charges in
a "coordinate-independent" symplectic-geometry type of approach and find
results that are consistent with the ones of hep-th/0607221.
