SUMMARY:Hunting De Sitter Holography from the Bottom Up
DESCRIPTION:Featuring Matthew Baumgart\, Carnegie Mellon University\n\nPart
	 of the HET Seminar Series.\n\nAbstract:\nThe holographic RG of Anti-De Sit
	ter gives a powerful clue about the underlying AdS/CFT correspondence. The 
	question is whether similar hints can be found for the heretofore elusive h
	olographic dual of De Sitter. The framework of stochastic inflation uses a 
	nonperturbative insight in order to tame bad behavior in the perturbation s
	eries at late times.  Recasting this as a "resummation of time"\, we w
	ish understand whether the distributions that result can be thought of as a
	n attractive UV fixed point of a theory living on a spacelike slice of DS. 
	  I will discuss our rederivation of stochastic inflation in terms of 
	wavefunctionals\, the straightforward way one can implement corrections to 
	the leading approximations\, and the robustness of the late-time equilibriu
	m to perturbations.
