DESCRIPTION:Inflation is the leading paradigm for explaining the origin of
  primordial fluctuations which seeds the creation of galaxies. These primo
 rdial fluctuations are encoded in a cosmological wavefunction. In this tal
 k I will discuss how to compute the wavefunction using the cosmological bo
 otstrap\, which is a series of constraints from fundamental physical princ
 iples. These include unitarity\, which results in the cosmological optical
  theorem\, as well as locality\, which results in the manifest locality te
 st. I will also discuss recent progress on understanding the analytic stru
 cture of the wavefunction\, which paves the way to establishing positivity
  bounds for cosmology.\n
