Cosmological Perturbations via Quantum Corrections in M-theory
Kazuho Hiraga, Yoshifumi Hyakutake
In the early universe it is important to take into account quantum effect of the gravity to explain the feature of the inflation. In this paper, we consider the M-theory effective…

Scalar Cosmological Perturbations in M-theory with Higher Derivative Corrections
Kazuho Hiraga, Yoshifumi Hyakutake
We investigate the inflationary expansion of the universe induced by higher curvature corrections in M-theory. The inflationary evolution of the geometry is discussed in ref.[1], t…

Inflationary Cosmology via Quantum Corrections in M-theory
Kazuho Hiraga, Yoshifumi Hyakutake
We investigate inflationary cosmology by solving the effective action of the M-theory, which consists of the 11 dimensional supergravity and quartic terms of the Weyl tensor. The m…
