Scale dependence of the power spectrum of the curvature perturbation determined using a numerical method in slow-roll inflation
Shiro Hirai, Tomoyuki Takami
The Taylor expansion method has been used to investigate the scale dependence of the power spectrum of the curvature perturbation. In the present study, an alternative numerical me…
