Fluctuations of FRW (Friedmann-Robertson-Walker) cosmological models with matter energy tensor corresponding to \(n\) minimally coupled massless scalar fields are studied. Exact solutions representing motion around the equilibrium points of a generic potential are found, and the asymptotic behaviour of perturbations that depend on the type of the fixed point is analyzed.
