Summary
In the limit for «small» quantum fields and pointlike charged particles we have heuristically shown the quantum-mechanical equivalence of a previously suggested nonlinear formulation of electrodynamics with the usual Lagrangian formulation of the electromagnetic with the usual Lagrangian formulation of the electromagnetic interaction of a charged scalar field.
Riassunto
Nel limite di campi quantizzati «piccoli» e di particelle cariche puntiformi, si mostra euristicamente l’equivalenza quantomeccanica di una formulazione non lineare dell’elettrodinamica proposta in precedenza con la usuale formulazione lagrangiana dell’interazione elettromagnetica di un campo scalare carico.
