DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/31/
 ">Narain to Narnia</a>\nby Nathan Benjamin (Princeton) as part of Kadanoff
  seminars\n\n\nAbstract\nWe generalize the recent holographic corresponden
 ce between an ensemble average of free bosons in two dimensions\, and a Ch
 ern-Simons-like theory of gravity in three dimensions\, by Afkhami-Jeddi e
 t al and Maloney and Witten. We find that the correspondence also works fo
 r toroidal orbifolds\, but we run into difficulties generalizing to K3 and
  Calabi-Yau sigma models. For the case of toroidal orbifolds\, we extend t
 he holographic correspondence to averages of correlation functions of twis
 t operators by using properties of rational tangles in three-dimensional b
 alls and their covering spaces. Based on work to appear with C. Keller\, H
 . Ooguri\, and I. Zadeh.\n
