One of us (R.F.A.-E.) is grateful to the Council for International Exchange of Scholars (CIES) for support through a Fulbright/MEC grant, and to Professor B. Zumino for the kind hospitality extended to him at the Theoretical Physics Group, Lawrence Berkeley Laboratory.It is shown that thermo-field dynamics permits the extension of the path integral methods used to solve the Thirring model at zero temperature to the finite temperature case. A family of exact solutions for the propagator and their dependence with temperature is given.journal articlehttp://dx.doi.org/10.1016/0370-2693(86)90106-1http://www.sciencedirect.commetadata only access53PhysicsMultidisciplinaryFísica (Física)22 Física
