Abstract
The partition functions for a family of 2-dimensional interacting theo ries containing the gauged Thirring model are computed. We obtain non- perturbative expressions for the dependence of the chiral condensate o n the temperature and the curvature. Both, high temperature and big cu rvature suppress the condensate exponentially and we can associate an effective temperature to the curvature.
