Punctuated eternal inflation via AdS/CFT
  The work is an attempt to model a scenario of inflation in the framework of
Anti de Sit- ter/Conformal Field theory (AdS/CFT) duality, a potentially
complete nonperturbative description of quantum gravity via string theory. We
look at bubble geometries with de Sitter interiors within an ambient
Schwarzschild anti-de Sitter black hole spacetime and obtain a characterization
for the states in the dual CFT on boundary of the asymptotic AdS which code the
expanding dS bubble. These can then in turn be used to specify initial
conditions for cosmology. Our scenario naturally interprets the entropy of de
Sitter space as a (logarithm of) subspace of states of the black hole
microstates. Consistency checks are performed and a number of implications
regarding cosmology are discussed including how the key problems or paradoxes
of conventional eternal inflation are overcome.
