Cosmic No-Hair Conjecture In Scalar-Tensor Theories

摘要

We have shown that, within the context of Scalar-Tensor theories, theanisotropic Bianchi-type cosmological models evolve towards de Sitter universe.A similar result holds in the case of cosmology in Lyra manifold. Thus theanalogue of cosmic no-hair theorem of Wald (1983) hold in both the cases. Infact, during inflation there is no difference between scalar-tensor theories,Lyra's manifold and general relativity (GR).
