Abstract
En 中文
The Thirring Model and various generalizations of it are analyzed in detail. The four-fermi interaction modifies the equation of state. Chemical potentials and twisted boundary conditions both result in complex fermionic determinants which are computed. The nonminimal coupling to gravity leads to a deformation of the conformal algebra which in particular contains the minimal models. We compute the central charges, conformal weights and finite size effects. For the gauged model we derive the partition functions and the explicit expression for the chiral condensate at finite temperature and curvature. The Bosonization in compact curved space-times is also explained. (C) 1996 Academic Press, Inc.
