Abstract:

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. It is proved that when k= -1 and k = 0 only one physical asymptotic behavior is possible: the radius of the universe expands forever. When k = 1 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.
