Asymptotic behavior of FRW cosmologies with many scalar fields
The dynamical evolution of FRW cosmologies conformally coupled to a finite set of scalar fields is studied. The scalar fields interact between them and we also consider a self-interaction term. lt is proved that when (Formula presented) and (Formula presented) only one physical asymptotic behavior i...

| 520 | 3 | |a The dynamical evolution of FRW cosmologies conformally coupled to a finite set of scalar fields is studied. The scalar fields interact between them and we also consider a self-interaction term. lt is proved that when (Formula presented) and (Formula presented) only one physical asymptotic behavior is possible: the radius of the universe expands forever. When (Formula presented) either we have the just described behavior or the universe will ultimately collapse in a finite time. But we also give evidence that an oscillatory chaotic behavior is possible in this case if a fine-tuning between the initial conditions is satisfied. © 2001 The American Physical Society. |l eng | |
