摘要
Some exact solutions in the Brans-Dicke (BD) theory are shown for a Bianchi V metric having the properties of inflationary expansion, graceful exit and asymptotic evolution to a Friedmann-Robertson-Walker open model. It is remarkable that inflationary behaviour can occur, even without a cosmological potential or constant. However the horizon and flatness problems cannot be solved within the standard ED theory because the inflationary period is severely restricted by the value of the ED parameter omega.
