Mutated hybrid inflation in -gravity
Masao Iihoshi
A new hybrid inflationary scenario in the context of -gravity is proposed. Demanding the waterfall field to 'support the potential from below' [unlike the original pr…
More on the dilatonic Einstein-Gauss-Bonnet gravity
Masao Iihoshi
Einstein-Gauss-Bonnet gravity coupled to a dynamical dilaton is examined from the viewpoint of Einstein's equivalence principle. We point out that the usual frame change that appli…
On the quartic curvature gravity in the context of FRW cosmology
M. Iihoshi, S. V. Ketov
We consider the purely gravitational fourth-order (in the spacetime curvature) quantum corrections to the Einstein-Hilbert gravity action, coming from superstrings in the leading o…
On the superstrings-induced four-dimensional gravity, and its applications to cosmology
Masao Iihoshi, Sergei V. Ketov
We review the status of the fourth-order (quartic in the spacetime curvature) terms induced by superstrings/M-theory (compactified on a warped torus) in the leading order with resp…
Conformally flat FRW metrics
Masao Iihoshi, Sergei V. Ketov, Atsushi Morishita
We find a new family of non-separable coordinate transformations bringing the FRW metrics into the manifestly conformally flat form. Our results are simple and complete, while our…
