Abstract
Evolution of the power spectrum is studied for non-Gaussian models of struc ture formation. We generalize the dark-matter approach to these models and find that the evolved spectrum at a weakly nonlinear regime is mainly deter mined by a simple integral of the dark-matter halo mass function in this ap proach. We also study the change of the nonlinear spectrum within the curre nt observational constraint of the primordial non-Gaussianity.
