Transformation de Fourier sur le groupe conforme

Преобразование Фурье на конформной группе

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

Summary

We introduce a conformally flat space-time related to Minkowski’s universe in which the special conformal group acts as a translation group which makes possible to define the Fourier transform on the conformal group. It is proved that the Fourier transform makes easier the check of the conformal covariance of field equations.

Résumé

On introduit on espace plat équivalent conforme à l'univers de Minkowski dans lequel le groupe conforme spécial opère comme un groupe de translation ce qui permet de définir la transformation de Fourier sur le groupe conforme. On montre que l'utilisation de la transformée de Fourier facilite l'étude de la covariance conforme.

Riassunto

Si introduce uno spazio-tempo piano conformemente equivalente all'universo di Minkowski in cui il gruppo conforme speciale opera come un gruppo di traslazione che permette di definire la trasformata di Fourier sul gruppo conforme. Si evidenzia come l'utilizzazione della trasformata di Fourier faciliti lo studio della covarianza conforme.

Резюме

Мы вводим конформно пллское пространство-время, связанное с вселенной Минковского, в которой специальная конформная группа действует, как группа трансляций, которая позволяет определить Фурье-преобразование на конформной группе. Доказывается, что преобразование Фурье позволяет легко проверить конформную ковариантность уравнений поля.
