Article

Summary

Energy sectors for solutions of nonlinear field equations are defined and their structure is investigated. The properties of dynamical charges contained in a given sector, their relations with symmetry groups and the breaking of local internal symmetries in a pure phase are discussed.

Динамические заряды и симметрии в нелинейной классической теории поля

Резюме

Опеделяются энергетические секторы для решений нелинейных полевых уравнений. Исследуется структура этих секторов. Обсуждаются свойства динамических зарядов, содержащихся в заданном секторе, их связь с группами симметрий и нарушение локальных внутренних симметрий в чистой фазе.

Riassunto

Si definiscono i settori di energia per le soluzioni di equazioni di campo non lineari, e se ne studia la struttura. Si discutono inoltre le proprietà delle cariche dinamiche contenute in un dato settore, le loro relazioni con gruppi di simmetria e la rottura di simmetrie locali interne in una fase pura.
