Abstract
We show how to extend the standard functional approach to bosonisation
, based on a decoupling change of path-integral variables, to the case
in which a finite temperature is considered. As examples, in order to
both illustrate and check the procedure, we derive the thermodynamica
l partition functions for the Thirring and Schwinger models. (C) 1998
