摘要：
Effective mass and energy are investigated using the Schwinger-Dyson equation (SDE) in the complex plane. As simple examples, we solve the SDE for the (1+1)-dimensional model and strongly coupled quantum electrodynamics (QED). We also study some properties of the effective mass and energy in the complex plane.
