Abstract: (Grobid)
We discuss the impact of Lorentz violation on the cosmology. Firstly, we showthat the Lorentz violation affects the dynamics of the chaotic inflationarymodel and gives rise to an interesting feature. Secondly, we propose the Lorentzviolating DGP brane models where the Lorentz violating terms on the braneaccelerate the current universe. We conjecture that the ghost disappears in theLorentz violating DGP models.- talk: Niigata 2006/11/27
