Summary

In the theory of classical electron developed by one of the authors, to such a particle a de Sitter microuniverse is associated. The internal dynamics of the particle (considered as pointlike) takes place in this universe. In connection to the model of electron deriving from the above-mentioned theory, some geometrical properties of the de Sitter universe are studied and in particular his geodesical representation on a manifold (Castelnuovo universe) for which the geodesics are straight lines. The present paper allows us to clarify the mutual connections between the « internal » and the « external » (macroscopical) dynamics of the electron and consequently a better understanding of the physical meaning of the theory.

Riassunto

Nella tooria dell’elettrone classico sviluppata da uno degli autori, a questa particella risulta associato un microuniverso di de Sitter entro il quale ha luogo la dinamica interna della particella stessa considerata puntiforme. In relazione al modello dell’elettrone che da tale teoria scaturisce si studiano alcuno proprietà geometriche dell’universo di de Sitter e in particolare della sua rappresentazione geodetica su una varietà (universo di Castelnuovo) per la quale le geodetiche sono delle rette. Ciò permette di chiarire l’interconnessione fra la dinamica « interna » dell’elettrone e la sua dinamica « esterna » (moto macroscopico) e quindi di comprendere meglio il significato fisico della teoria.

Резюме

В теории классического электрона, развитой одним из авторов, такой частице сопоставляется микровселенная де Ситтера. Внутри этой вселенной имеет место внутренняя динамика частицы (рассматриваемой как точечная). В связи с моделью электрона, полученной ие. вышеуказанной теории, исследуются некоторые геометрические свойства вселенной де Ситтера и, в частности, геодезическое представление вселенной на множестве (Вселенная Кастелнуово), для которого геодезические линии представляют прямые линии. Данная работа позволяет разъяснить взаимную связь « внутренней » и « внешней » (макроскопической) динамики электрона и, следовательно, лучше понять физический смысл теории.
