Can induced gravity isotropize Bianchi type I, V, or IX universes?

We analyze if Bianchi type I, V, and IX models in the induced gravity (IG) theory can evolve to a Friedmann-Roberson-Walker (FRW) expansion due to the nonminimal coupling of gravity and the scalar field. The analytical results that we find for the Brans-Dicke (BD) theory are now applied to the IG theory which has $\omega \ll 1$ (ω being the square ratio of the Higgs boson to Planck mass) in a cosmological era in which the IG potential is not significant. We find that the isotropization mechanism crucially depends on the value of $\omega .$ Its smallness also permits inflationary solutions. For the Bianchi type V model, inflation due to the Higgs potential takes place afterwards, and subsequently spontaneous symmetry breaking ends with an effective FRW evolution. The ordinary tests of successful cosmology are well satisfied.
