The non-Gaussianity of the primordial cosmological perturbations will be strongly constrained by future observations. It will provide us with important information about the early universe and will be used to discriminate among models. In view of these observations, I will study the evolution of second order scalar perturbations from inflation to the late time universe, in the matter dominated era.
