Scientific paper

We have found the most general solution for the Bianchi type-I equations in the Brans-Dicke theory (BDT) for the vacuum case. It is shown that for w greater than 500 the universe will become isotropic for any amount of initial anisotropy. Secondly, it is shown that in the extended inflation scenario the BDT-scalar field phi can avoid the inflation in one direction, R3. In the other scale factors R1 and R2 there is inflationary expansion.
