Matching of schwarzschild’s and friedmann’s fields in synchronous coordinates

согласование полей Ъварцщильда и фридмана в синхронных координатах

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

Summary

In synchronous coordinates the junction conditions of gravitational fields in general relativity are studied and formulated in a theorem. A new convenient procedure was formulated and used to match Schwarzschild’s and Friedmann’s fields for negative, zero and positive curvature.

Riassunto

Si studiano e si formulano in un teorema le condizioni di giunzione, in coordinate sincrone, di campi gravitazionali nella relatività generale. È stato elaborato e usato un nuovo utile procedimento per adattare i campi di Schwarzschild e Friedmann per curvatura negativa, nulla e positiva.

Реэуме

в синхронных координатах исследуются и формулируются условия контакта гравитационных полей в обшей теории относительности. Предлагается и испольэуется новая процедура для согласования полей ъварцщильда и фридмана для отрицательной, нулевой и положительной кривиэны.
