  The low temperature properties of the SU(N) Wolff impurity model are studied
via Abelian bosonization. The path integral treatment of the problem allows for
an exact evaluation of low temperature properties of the model. The single
particle Green's function enhances due to the presence of local correlation.
The basic correlation function such as the charge or spin correlator are also
influenced by the presence of impurity, and show local Fermi liquid behaviour.
The X-ray absorption is affected by the presence of local Hubbard interaction.
The exponent is decreased (increased) for repulsive (attractive) interactions.
