DESCRIPTION:Austin Joyce (University of Amsterdam)\nThe large-scale correl
 ations that we observe in the distribution of matter in the universe have 
 their origins in primordial perturbations produced prior to the hot big ba
 ng—likely during a period of inflationary expansion. Interestingly we do
  not directly observe the inflationary epoch\, but instead infer its dynam
 ics from correlations residing on the late time boundary of the inflationa
 ry spacetime\, where the universe reheats. This motivates us to ask whethe
 r we can understand things directly on this asymptotic boundary\, without 
 making explicit reference to bulk time evolution. I will describe recent p
 rogress in this direction\, including aspects of how the bulk dynamics is 
 encoded on the boundary.\n\nThe recording will be available at https://me
