DESCRIPTION:Sander Mooij (Universidad de Chile)\nIn non-attractor models o
 f inflation the curvature perturbation does not freeze but continues to ev
 olve on superhorizon scales\, even in a single-field setup. Due to this pe
 culiar behaviour\, Maldacena’s consistency relation\, which relates the 
 inflationary bispectrum in the squeezed limit to the power spectrum and th
 e spectral index\, breaks down. In this talk\, I show how the superhorizon
  non-freezing can be understood from symmetry arguments\, and derive a new
  relation for the bispectrum’s squeezed limit valid for general non-attr
 actor models of inflation.
