Towards Anisotropy-Free and Non-Singular Bounce Cosmology with
  Scale-invariant Perturbations
  We investigate non-singular bounce realizations in the framework of
ghost-free generalized Galileon cosmology, which furthermore can be free of the
anisotropy problem. Considering an Ekpyrotic-like potential we can obtain a
total Equation-of-State (EoS) larger than one in the contracting phase, which
is necessary for the evolution to be stable against small anisotropic
fluctuations. Since such a large EoS forbids the Galileon field to generate the
desired form of perturbations, we additionally introduce the curvaton field
which can in general produce the observed nearly scale-invariant spectrum. In
particular, we provide approximate analytical and exact semi-analytical
expressions under which the bouncing scenario is consistent with observations.
Finally, the combined Galileon-curvaton system is free of the Big-Rip after the
bounce.
