Abstract
We study the influence of on-site disorder on the magnetic properties of th e ground state of the infinite-LI one-dimensional (1D) Hubbard model. We fi nd that the ground state is not ferromagnetic. This is analysed in terms bf the algebraic structure of the spin dependence of the Hamiltonian. A simpl e explanation is derived for the 1/N periodicity in the persistent current for this model.
