| Sumario: | 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. |
