55. Eternal inflation: stochastic approach 3 (Inflationary perturbations 7)

Last time we have found that dynamics of the inflaton field (more precisely, its expectation value w.r.t. to the distribution among different Hubble patches) is determined by the Langevin equation. (…)


54. Eternal inflation: stochastic approach 2 (Inflationary perturbations 7)

In the previous post we have started to discuss the regime of eternal inflation realized when classical displacement of the inflaton field becomes comparable with the average amplitude of fluctuations generated at super-Hubble scale. (…)
