SUMMARY:Beyond perturbation theory in inflation - Paolo Creminelli (ICTP\,

DESCRIPTION:Deviations from Gaussianity in inflation are usually calculate
 d using perturbation theory. This method\, however\, fails for unlikely ev
 ents on the tail of the probability distribution\, like the formation of a
  primordial black hole. I explain how one can explore these unlikely event
 s using semiclassical methods and then discuss the case of resonant non-Ga
 ussianity.
