✦ Synopsis

We consider the general behaviour of cosmologies in Brans Dicke theory where the dilaton is self-interacting via a potential V(8). We show that the general radiation universe is a two-dimensional dynamical system, whereas the dust or false vacuum universe is threedimensional. This is in contrast to the non-interacting dilaton which has uniformly a twodimensional phase space. We find the phase spaces in each case and the general behaviour of the cosmologies.

Solutions to flat space Friedmann Robertson Walker cosmologies in Brans Dicke theory with a cosmological constant are investigated. The matter is modeled as a #-law perfect fluid. The field equations are reduced from fourth order to second order through a change of variables, and the resulting two-d
