DESCRIPTION:De Sitter Wavefunctionals and the Resummation of Time\n\nThe ho
 lographic RG of Anti-De Sitter gives a powerful clue about the underlying 
 AdS/CFT correspondence.  The question is whether similar hints can be foun
 d for the heretofore elusive holographic dual of De Sitter. The framework 
 of stochastic inflation uses nonperturbative insight to tame bad behavior 
 in the  perturbation series of a massless scalar in DS at late times.  Rem
 arkably\, this fully quantum system loses phase information in the leading
  approximation\, but retains a probabilistic character and allows for a co
 ntrolled  prediction of late time Green's functions.  Recasting this as a 
 "resummation of time"\, we wish \nunderstand whether the distributions tha
 t result can be thought of as an attractive UV fixed point of a theory  li
 ving on a spacelike slice of DS.  We derive stochastic inflation via novel
  statements to all orders in perturbation theory and the wavefunctional ap
 proach to Quantum Field Theory.  This allows for the straightforward imple
 mentation of corrections to the original framework.
