Summary
It is proved that the combined neutrino gravitational field equations in general relativity admit no nontrivial solutions in a static space-time provided that the energy flow vector of the neutrino field is timelike or null for all observers.
Riassunto
Si dimostra che le equazioni del campo neutrino-gravitazionale combinate in relatività generale non ammettono alcuna soluzione ovvia in uno spazio-tempo statico purché il vettore di flusso dell’energia del campo del neutrino sia temporale oppure nullo per tutti gli osservatori.
Резюме
Доказывается, что комбинированные уравнения для гравитационного и нейтринного полей в общей в общей теории относительности не допускают нетривиальных решений в статическом пространстве-времени, при условии, что вектор потока энергии для нейтринного поля является времени-подобным или нулевым для всех наблюдателей.
