DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/100/">
 Burns space and celestial holography</a>\nby Kevin Costello (Perimeter Ins
 titute) as part of NHETC Seminar\n\n\nAbstract\nCelestial holography aims 
 to describe scattering amplitudes of theories on asymptotically flat space
  times in terms of two-dimensional CFTs. I will describe an explicit top-d
 own example\, where correlators of a 2d chiral CFT at large N match amplit
 udes of a 4d theory on an asymptotically flat manifold known as Burns spac
