Yosuke Misonoh (Waseda University) 13:30- "Cosmic no-hair conjecture and anisotropic inflation" Recent precise cosmoligical observation reveals that the universe has a per cent level of anisotropy on a large angular scale. This fact is not compatible with the inflational scenario because of the cosmic no-hair conjecture, which predicts anisotropy and inhomogeneity are vanished in late time. Thus in order to explatin large scale anisotropy, we may need to reconsider the very early era of the universe. In this presentation, I would like to review the cosmic no-hair conjecture and its counter examples. the references are as follows: [1] G.F.R.Ellis and M.A.H.MacCallum, Commun. Math.
