Abstract

This review is centered on the properties and mechanisms underlying the generation of perturbations in models of the early Universe with conformal invariance, which could be alternatives to inflation. A detailed analysis of the properties of primary scalar perturbations, i.e., power spectrum, statistical anisotropy, and non-Gaussianity is performed within the framework of these models. Properties of primary gravitational waves are also considered.
