Description
I discuss the curvature perturbation and the delta-N
formalism, with
focus on observationally relevant non-gaussianities,
which may be
generated either during inflation or at the end of
inflation.
Modelling attempts involve both inflatons and
spectators. I emphasize
the importance of understanding the decay mechanisms
of the inflaton;
examples are modulated reheating and preheating. I
also discuss
briefly isocurvature perturbations.
