ABSTRACT. We consider gapless models of statistical mechanics. At zero
temperatures correlation functions decay asymptotically as powers of
distance in these models. Temperature correlations decay
exponentially. We used an example of solvable model to find the
formula, which describes long distance and large time asymptotic of
correlation function of local fields. The formula describes
correlation at any temperature and arbitrary coupling constant.
