Description

In this dissertation, in order to study the growth of the density fluctuations of the Cold Dark Matter, the standard perturbation techniques, such as Eulerian perturbation theory and Zel’dovich approximation, have been reviewed. In the second part of this work, we introduce a novel approach to the study of large–scale structure formation in which the Cold Dark Matter is modelled by a complex scalar field whose dynamics are ruled by cou- pled Schrödinger and Poisson equations. In the last part, we show that the lowest order cumulants of Eulerian perturbation theory for the Cold Dark Matter are perfectly recovered.
