Модель алгебры токов, основанная на волновом уравнении

Summary

A simple finite-component model withcompletely nontrivial currents is constructed, which are explicitly shown to satisfy the charge-current algebra in the infinite-momentum limit. It is argued, that the same construction applies to a large class of physically more relevant infinite-component models, which receive only negligible contributions from spacelike solutions.

Riassunto

Si costruisce un semplice modello a componenti finite con correnti completamente non banali, che, si dimostra esplicitamente, soddisfano l’algebra delle correnti di carica nel limite di quantità di moto infinita. Si deduce che la stessa costruzione si applica ad un’ampia classe di modelli a componenti infinite fisicamente più importanti, che ricevono solo contributi trascurabili dalle soluzioni spaziali.

Реэуме

Конструируется простая модель, с конечным числом компонент, сполностью нетривиалными токами, которая, как покаэывается в явной форме, удовлетворяет алгебре эаряженных токов в пределе бесконечного импульса. Докаэывается, что такая конструкция применима к больщому классу фиэически более уместных моделей с бесконечным числом компонент, которые получают лищь бесконечно малые вклады от пространственно-под обных рещений.
