Cosmological perturbations in warm-tachyon inflationary universe model with viscous pressure on the brane

Setare, M. R., Kamali, V.

Understand

We study warm-viscous inflationary universe model on the brane, in a tachyon field theory.

  • We obtain the general conditions which are required for this model to be realizable.
  • In longitudinal gauge, the primoradial perturbation parameters are found in great details, using slow-roll and quasi-stable approximations.
  • The general expressions of the tensor-to-scalar ratio, scalar spectral index and its running are found.
