Summary
The aim of this paper is to apply the generalized zetafunction to the regularization of the effective potential. This method is exemplified by the calculation of the one-loop effective potential at finite temperature and in an uniform magnetic field in a few models of field theory. The zeta-function regularization avoids the subtraction of any pole term or the addition of infinite counterterms.
Riassunto
Lo scopo di questo articolo è di applicare la funzione zeta generalizzata alla regolarizzazione del potenziale effettivo. Questo metodo è esemplificato dal calcolo del potenziale effettivo a un cappio a temperatura finita e in un campo magnetico uniforme in alcuni modelli di teoria dei campi. La regolarizzazione della funzione zeta evita la sottrazione di qualsiasi termine polare o l’addizione di controtermini infiniti.
Резюме
Цель зтой статьи—иснользовать обобщенную дзета-функцию для регуляризации зффективного потенциала. Этот метод иллюстрируется с помощью вычисления эффективного потенциала с одной петлей при конечных температурах и в однородином магнитном поле. Регуляризация с помощью дзетафункции позволяет избежать вычитаний полюсных членов ияи добавления бесконечных контр-членов.
