Abstract


Introduction/purpose: The problem of quantum corrections to propagators in Quantum Electrodynamics (QED) is discussed.

Methods: The Dyson–Schwinger equation is employed for correcting
propagators in QED.

Results: The observable quantities in QED are finite.

Conclusions: QED divergencies can be avoided by redefining physical
quantities in a suitable manner
