DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UKYhepth/6/"
 >Gravity from Averaging CFTs</a>\nby Alexander Maloney (McGill University)
  as part of Theoretical Physics Seminars (Kentucky)\n\n\nAbstract\nI will 
 explore the idea that certain theories of gravity in Anti-de\nSitter space
  are dual to an average over an ensemble of quantum\ntheories\, rather tha
 n to a specific quantum theory.  I will describe\nan average over Narain
 ’s family of two-dimensional conformal field\ntheories which describe fr
 ee bosons on a torus\, and compute the\npartition function using the Siege
 l-Weil formula.  The result takes\nthe form of a sum over geometries as on
 e would expect in a theory of\ngravity.  But the gravitational theory look
 s more like a Chern-Simons\ntheory than like Einstein gravity.\n
