Research Abstract |
We study most fundamental and important subjects on cosmology as gravitational physics. As for the subject on the early universe, we analyze the so called cosmological singularity problem by Horava-Lifshitz gravity theory and the origin of inflation based on superstring theory. We also study dark energy problem mainly by a bigravity theory. We find that dark energy (a cosmological constant) naturally appears as an attractor in this model.
