Evolution of inhomogeneous plane-symmetric cosmological models

  • N. Tomimura
Article

Summary

The models are solutions of Einstein's equations for dust with plane symmetry. For the particular caseK=0, a new solution is found. This solution depends on one arbitrary function which evolves to the open Robertson-Walker model ast→∞, but whose density on an initial spacelike hypersurface is an arbitrary function ofz.

Эволюция неоднородных плоскосимметричных космологических моделей

Резюме

Для случаяK=0 получено новое решение для неоднородной плоскосимметричной пылевой модели. Возможности эволюции оказываются различными. Получен результат, что открытая модель Фридмана может эволюционировать из множества начальных состояний.

Riassunto

I modelli sono soluzioni di equazioni di Einstein per polvere a simmetria piana. Per il caso particolareK=0, si trova una nuova soluzione. Questa soluzione dipende da una funzione arbitraria che evolve verso il modello di Robertson e Walker pertр∞, ma la cui densità su un'ipersuperficie iniziale del tipo spazio è una funzione arbitraria diz.
