Is brane inflation eternal? [PDF]
Journal of Cosmology and Astroparticle Physics, 2006 In this paper, we show that eternal inflation of the random walk type is generically absent in the brane inflationary scenario. Depending on how the brane inflationary universe originated, eternal inflation of the false vacuum type is still quite possible.

, 2009 This volume is the only monograph covering the exciting and dazzling recent developments in quantum cosmology, including the theory of the "multiverse" and eternal inflation pioneered by A Vilenkin, A Linde, S W Hawking, and others.

A smooth exit from eternal inflation?
Journal of High Energy Physics, 2018 The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation.

Inflation and eternal inflation [PDF]
Physics Reports, 2000 The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that ...

Classical and Quantum Gravity, 2014 We propose a new measure for eternal inflation that includes both conditions, large field fluctuations and smooth homogeneous domains, in the self reproducing probability estimate. We show that due to the increasing inhomogeneities in the background spacetime fractal, self-reproduction stops within a finite time t_f, thus inflation can not be eternal.

Annals of the New York Academy of Sciences, 2001 Abstract: The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. It is argued that essentially all inflationary models lead to (future‐)eternal inflation, which implies that an infinite number of pocket universes are produced.

The cosmological model of eternal inflation and the transition from chance to biological evolution in the history of life [PDF]
Biology Direct, 2007 Background Recent developments in cosmology radically change the conception of the universe as well as the very notions of "probable" and "possible". The model of eternal inflation implies that all macroscopic histories permitted by laws of physics are ...

Holographic (eternal) inflation
Journal of High Energy PhysicsWe identify a minisuperspace of complex deformations of ABJM theory for which the partition function specifies the amplitude of an eternally inflating universe.

Eternal hilltop inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 We consider eternal inflation in hilltop-type inflation models, favored by current data, in which the scalar field in inflation rolls off of a local maximum of the potential. Unlike chaotic or plateau-type inflation models, in hilltop inflation the region of field space which supports eternal inflation is finite, and the expansion rate $H_{EI}$ during ...
