SUMMARY:Twisted holography in AdS3/CFT2 - Natalie Paquette (University of 
 Washington)

DESCRIPTION:We will explore twisted holography in the context of classical
  examples of AdS/CFT\, namely AdS3 x S3 x T^4 and AdS3 x S3 x K3. We will 
 introduce the twisted dual pair and sketch some basic sanity checks of the
  duality. Then\, we will explain how the technique of Koszul duality appli
 ed to twisted holography can be used to completely determine the planar 1/
 4-BPS 2 and 3-point functions analytically. Unlike in most examples of Kos
 zul duality computations\, even planar computations require the evaluation
  of (holomorphic) integrals\, to perturbatively account for the backreacti
 on from flat space to AdS space\, although miraculously this truncates to 
 only three diagrams as N goes to infinity. 1/4-BPS states in AdS3/CFT2 fur
 nish a chiral algebra in the twisted duality\, so this computation boils d
 own to the extraction of planar chiral algebra OPEs.&nbsp\;&nbsp\;
