Abstract

This paper provides a review of the types of dark matter that are thought to be fundamental components of the Universe, and their role in the origin and evolution of structures, together with some new original results concerning improvements to the spherical collapse model. In particular, we show how the spherical collapse model is modified when dynamical friction and tidal torques are taken into account.
