An analytic expression for the Green's function of the ground state of the finite one-dimensional Hubbard model and the density of the electronic states on the sites are obtained. It is ehown that the introduction of a local perturbation can cause the formation of quasilocalized levels which may transform into localized states when the pertubation reaches some critical value.Es wird ein analytischer Ausdruck fur die Greensche Funktion des Grundzustands des endlichen eindimensionalen Hubbard-Modells und die Dichte der elektronischen Zustande erhalten. Es wird gezeigt, daf3 die Einfuhrung einer lokalen Storung die Bildung von quasilokalisierten Niveaus verureachen kann, die in lokalisierte Zustiinde ubergehen konnen, wenn die Storung einen kritischen Wert erreicht.
