Abstract
We consider the non-Abelian Hubbard chain in a magnetic field and chem ical potential. We find that the set of different pseudoparticle types which generate the ground state from the suitable vacuum transform in the representation of the symmetry group U(1)circle times U(1), SU(2) circle times U(1), U(1)circle times SU(2), or SO(4) of the correspondi ng sector of parameter space.
