چکیده
A finite chain calculation in terms of Hubbard X-operators is explored by setting
up a vibronic Harniltonian. The model conveniently transformed into a form so that
in the case of strong coupling a numerical renormalization group approach is
applicable. To test the technique, a one particle Green function is calculated for the
model Harniltonian
