Abstract
In the course of evaluating the functional integral for the
classical partition function for the sine-Gordon model, we found
`beyond all orders' low temperature strictly asymptotic expansions for
ln Z which are also found to be the iteration of a system of coupled
non-linear integral equations. Thus the asymptotic expansions are
`summable' to these coupled integral equations
