Holography for the very early Universe and the classic puzzles of Hot
  Big Bang cosmology
  We show that standard puzzles of hot Big Bang cosmology that motivated the
introduction of cosmological inflation, such as the smoothness and horizon
problem, the flatness problem and the relic problem are also solved by
holographic models for very early universe based on perturbative three
dimensional QFT. In the holographic setup, cosmic evolution is mapped to
inverse renormalization group (RG) flow of the dual QFT, and the resolution of
the puzzles relies on properties of the RG flow.
