Effect of initial condition of inflation on power and angular power spectra in finite slow-roll inflation
Shiro Hirai, Tomoyuki Takami
The effect of the initial condition of inflation on the power spectra of scalar and tensor perturbations is estimated assuming a slow-roll inflation model. By defining a more gener…

Length of inflation and WMAP data in the case of power-law inflation
Shiro Hirai, Tomoyuki Takami
The effect of the length of inflation on the power spectra of scalar and tensor perturbations is estimated using the power-law inflation model with a scale factor of a(t) = t^q. Co…

Pre-inflation models and WMAP data
Shiro Hirai
The effect of pre-inflation physics on the power spectrum of scalar perturbations is estimated and there is a possibility that the pre-inflation physics explains the Wilkinson Micr…
