Summary
The field equations of Yilmaz’ new approach to general relativity are extended to the case when matter is present and are used to find cosmological models. It is shown that the theory includes both steady-state and Robertson-Walker type models which are not the same as those found in the usual relativistic cosmology.
Riassunto
Si estendono le equazioni di campo di Yilmaz al caso in cui è presente materia e le si usa per trovare modelli cosmologici. Si dimostra che la teoria comprende sia il modello del tipo di Robertson-Walker sia quello del tipo a stato stazionario, e che questi modelli non sono gli stessi ottenuti conunemente in cosmologia relativistica.
Резюме
Уравнения поля нового подхода йилмаца к общей теории относительности распространяются на случай, когда присутствует вещество. Эти уравнения используются для получения космологических моделей. Показывается, что эта теория включает и модель стационарного состояния и модель типа Робертсона-Уокера, которые не похожи на модели, полученные в обычной релятивистской космологии.
