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
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
