Stability properties of some perfect fluid cosmological models
Vittorio Gorini, Alexander Kamenshchik, Ugo Moschella +2
Flat FRW perfect fluid cosmologies can be reproduced as particular solutions of suitable field theoretical models. Here we investigate the stability of perfect fluid model trajecto…
