摘要：
The partition functions for a family of 2-dimensional interacting theories containing the gauged Thirring model are computed. We obtain non-perturbative expressions for the dependence of the chiral condensate on the temperature and the curvature. Both, high temperature and big curvature suppress the condensate exponentially and we can associate an effective temperature to the curvature.
