Isotropization in bianchi typeI vacuum cosmology
Abstract
We have found the most general solution for the Bianchi typeI equations in the BransDicke theory (BDT) for the vacuum case. It is shown that forw > 500 the Universe will become isotropic for any amount of initial anisotropy, secondly it is shown that in the extended inflation scenario, the BDTscalar field φ can avoid the inflation in one direction,R _{3}. In the other scale factorsR _{1} andR _{2} there is inflationary expansion.
