Abstract: | The dynamics of a homogeneous, anisotropic, spatially flat Bianchi type I universe filled with a scalar field is studied. Using the usual synchronous form of the line element, general exact solutions for the Einstein field equations are obtained in the case of the exponential-potential scalar field (V=Λexp(k?)) and in the case of the Barrow-Saich potential ( $V sim dot varphi ^2 $ ). Conditions under which inflation can occur are discussed and the late-time behaviour of the models is also considered. |
