behaviour of a Fermi liquid at low temperatures can be described exactly
in terms of a number of renormalized parameters. These parameters are
difficult to calculate in strongly correlated systems, where the
interactions are so strong that direct perturbation theory cannot be
applied. The renormalized parameters, however, can be calculated from
non-perturbative numerical renormalization group (NRG) calculations for
certain impurity systems, and lattice models in infinite dimension, In the
strong correlation regime, and in the approach to a quantum critical
point, relations between the renormalized parameters can be predicted from
the conditions that certain types of fluctuations are suppressed. We show
that these relations are confirmed by direct NRG
calculations.<o:p></o:p></FONT></SPAN></B></P>

present a new way to calculate renormalized parameters using a
renormalized form of perturbation theory. We illustrate the approach for
the Anderson impurity model,and show that it gives good results in the
strong correlation regime. The method has potential for application to
more general class of strongly correlated electron systems, such as the
Hubbard and periodic Anderson models in three
dimensions.<o:p></o:p></FONT></SPAN></B></P>
