Abstract: (APS)

A nonperturbative method of solving the Dyson-Schwinger equations for the fermion propagator is considered. The solution satisfies the Ward-Takahashi identity, allows multiplicative regularization, and exhibits a physical-mass pole.

QUANTUM ELECTRODYNAMICS: NONPERTURBATIVE
ELECTRON: PROPAGATOR
RENORMALIZATION: REGULARIZATION
DYSON-SCHWINGER EQUATION: SOLUTION
GAUGE FIELD THEORY: WARD-TAKAHASHI IDENTITY
