Inflation from Superstring/M Theory Compactification with Higher Order Corrections I
Kei-ichi Maeda, Nobuyoshi Ohta
We study time-dependent solutions in M and superstring theories with higher order corrections. We first present general field equations for theories of Lovelock type with stringy c…
Creation of a brane world with Gauss-Bonnet term
Koh-suke Aoyanagi, Kei-ichi Maeda
We study a creation of a brane world using an instanton solution. We analyze a brane model with a Gauss-Bonnet term in a bulk spacetime. The curvature of 3-brane is assumed to be c…
Collision of Domain Walls and Reheating of the Brane Universe
Yu-ichi Takamizu, Kei-ichi Maeda
We study a particle production at the collision of two domain walls in 5-dimensional Minkowski spacetime. This may provide the reheating mechanism of an ekpyrotic (or cyclic) brane…
Domain Wall Dynamics in Brane World and Non-singular Cosmological Models
Naoya Okuyama, Kei-ichi Maeda
We study brane cosmology as 4D (4-dimensional) domain wall dynamics in 5D bulk spacetime. For a generic 5D bulk with 3D maximal symmetry, we derive the equation of motion of a doma…
Inflation from M-Theory with Fourth-order Corrections and Large Extra Dimensions
Kei-ichi Maeda, Nobuyoshi Ohta
We study inflationary solutions in the M-theory. Including the fourth-order curvature correction terms, we find three generalized de Sitter solutions, in which our 3-space expands…
