The aim of this disertation is the study of the evolution of cosmological perturbations, beyond the linear order, in universes characterized by non-zero spatial curvature. In particular, we will obtain the general equations for cosmological fluctuations, in Newtonian approximation and the second-order perturbative solutions. Finally, we will calculate the gravitational skewness of the cosmologiacal fields.
