We examine various entropic inflation scenarios, under the light of eternality. After describing the inflation realization and the normal condition for inflation to last at the background level, we in...
Present treatments of eternal in ation regulate in nities by imposing a geometric cuto . We point out that some matter systems reach the cuto in nite time. This implies a nonzero probability for a n...
In some well-known scenarios of open-universe eternal inflation, developed by Vilenkin and co-workers, a large number of universes nucleate and thermalize within the eternally inflating mega-universe....
The No-Boundary Measure in the Regime of Eternal Inflation

The no-boundary wave function (NBWF) specifies a measure for prediction in cosmology that selects inflationary histories and remains well behaved for spatially large or infinite universes. This paper ...
