The effects of anisotropy and non-adiabaticity on the evolution of comoving curvature perturbation

Atsushi Naruko, Antonio Enea Romano, Misao Sasaki +1

We derive the equation for the evolution of the curvature perturbation on the comoving time slice, ${\mathcal{R}}_c$, in the presence of anisotropic and non-adiabatic terms in the en…
