DESCRIPTION:Speakers: Bin Zhu (Edinburgh)\n\nIn recent years\, the relatio
 ns between asymptotic symmetries and soft theorems have led to a promising
  candidate for flat holography: celestial holography. The central objects 
 in this program are celestial amplitudes\, which behave as correlation fun
 ctions of primary operators in a putative conformal field theory: celestia
 l CFT (CCFT). In this talk\, we will first introduce some basics of celest
 ial amplitudes and CCFT\, including celestial operator product expansions 
 (OPEs). We will describe one specific example\, the celestial Liouville th
 eory for Yang-Mills amplitudes based on work with Stieberger and Taylor. W
 e will conclude with some open questions and future directions.\n\nhttps:/
