Summary

A concise and rigorous treatment is given of the infrared divergences of quantum electrodynamics, by using a technique previously developed in connection with ultraviolet renormalization. The result is essentially equivalent to an extension of the classical Bloch-Nordsieck formula, and is independent of perturbative methods.

Riassunto

Le divergenze infrarosse della elettrodinamica quantistica vengono trattate in modo rigoroso e conciso, mediante tecniche elaborate a scopo rinormalizzativo. Si ottiene, in modo indipendente da metodi perturbativi, la naturale estensione della formula classica di Bloch-Nordsieck.
