摘要：
We extend the Schwinger-Dyson equation (SDE) on the complex plane, which was treated in our previous research, to finite temperature. As a simple example, we solve the SDE for a model with four-fermion interactions in (1+1) space-time dimensions in the strong coupling region. We investigate the properties of the effective mass and energy for the fermions, especially near the phase transition temperature.
