DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/9/"
 >Gravity from Averaging CFTs</a>\nby Alex Maloney (McGill) as part of Kada
 noff seminars\n\n\nAbstract\nI will explore the idea that certain theories
  of gravity in Anti-de Sitter space are dual to an average over an ensembl
 e of quantum theories\, rather than to a specific quantum theory.  I will 
 describe an average over Narain’s family of two-dimensional conformal fi
 eld theories which describe free bosons on a torus\, and compute the parti
 tion function using the Siegel-Weil formula.  The result takes the form of
  a sum over geometries as one would expect in a theory of gravity.  But th
 e gravitational theory looks more like a Chern-Simons theory than like Ein
 stein gravity.\n
