Sakine Nishi, Tsutomu Kobayashi
We propose a novel branch of the Galilean Genesis scenario as an alternative to inflation, in which the universe starts expanding from Minkowski in the asymptotic past with a gross…

Cosmological matching conditions and galilean genesis in Horndeski's theory
Sakine Nishi, Tsutomu Kobayashi, Norihiro Tanahashi +1
We derive the cosmological matching conditions for the homogeneous and isotropic background and for linear perturbations in Horndeski's most general second-order scalar-tensor theo…
