Abstract (EN): We consider the general behaviour of cosmologies in Brans-Dicke theory where the dilaton is self-interacting via a potentialV(¿). We show that the general radiation universe is a two-dimensional dynamical system, whereas the dust or false vacuum universe is three- dimensional. This is in contrast to the non-interacting dilaton which has uniformly a two-dimensional phase space. We find the phase spaces in each case and the general behaviour of the cosmologies. © 1997 Academic Press.
