DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CCTP_HEP/9/"
 >Liouville theory and Matrix models - A Wheeler DeWitt perspective</a>\nby
  Panagiotis Betzios (University of Crete) as part of CCTP HEP Seminars\n\n
 \nAbstract\nWe analyse the connections between the Wheeler DeWitt approach
  for two dimensional quantum gravity and holography\, focusing mainly in t
 he case of Liouville theory coupled to c = 1 matter. Our motivation is to 
 understand whether some form of averaging is essential for the boundary th
 eory\, if we wish to describe the bulk quantum gravity path integral of th
 is two dimensional example. The analysis hence\, is in a spirit similar to
  the recent studies of Jackiw-Teitelboim (JT)-gravity. Macroscopic loop op
 erators define the asymptotic region on which the holographic boundary dua
 l is expected to reside. Matrix quantum mechanics (MQM) and the associated
  double scaled fermionic field theory on the contrary\, is providing an ex
 plicit "unitary in superspace" description of the complete dynamics of suc
 h two dimensional universes with matter\, including the effects of topolog
 y change. If we try to associate a Hilbert space to a single boundary dual
 \, it seems that it cannot contain all the information present in the non-
 perturbative bulk quantum gravity path integral and MQM.\n
