Query: Correlation functions of the integrable $SU(n)$ spin chain   We study the correlation functions of $SU(n)$ $n>2$ invariant spin chains in
the thermodynamic limit. We formulate a consistent framework for the
computation of short-range correlation functions via functional equations which
hold even at finite temperature. We give the explicit solution for two- and
three-site correlations for the $SU(3)$ case at zero temperature. The
correlators do not seem to be of factorizable form. From the two-sites result
we see that the correlation functions are given in terms of Hurwitz' zeta
function, which differs from the $SU(2)$ case where the correlations are
expressed in terms of Riemann's zeta function of odd arguments.
