A new and consistent method for classical renormalization

Новый и непротиворечивый метод для классической перенормировки

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

A general method, whose consistency was checked, is proposed for taking into account self-interaction in classical physics. The finite radiation terms are identical to those given by Dirac's method. Moreover, by means of analytic continuation, a formula is found which reduces the computation of self-interaction terms to mere inspection.

Riassunto

Si propone un modello generale, di cui è stata verificata la consistenza, per tener conto delle autointerazioni nella fisica classica. I termini di radiazione finiti risultano identici a quelli forniti dal metodo di Dirao. Inoltre, per mezzo della continuazione analitica, si trova una formula che riconduce il calcolo dei termini di autointerazione a una semplice ispezione.

Резюме

Предлагается общий метод, непротиворечивость которого проверяется, для рассмотрения собственного взаимодействия в классической физике. Конечные радиационные члены оказываются тождественными членам, которые получаются в методе Дирака. Кроме того, с помощью аналитического продолжения получается формула, которая сводит вычисление членов собственного взаимодействия к простому рассмотрению.

  6. This property is necessary for the method to give unambiguous results.

  7. Schumutzer ref. (5) has proposed to take into account self-interaction by means of such formal expansions in powers of σ, but it is easy to show that for higher derivatives such a procedure is not consistent in the sense emphasized here and moreover does not yield results in agreement with Dirac's.
