Non-Baryonic Dark Matter in Cosmology
  This paper is a broad-band review of the current status of non-baryonic dark
matter research. I start with a historical overview of the evidences of dark
matter existence, then I discuss how dark matter is distributed from small
scale to large scale, and I then verge the attention to dark matter nature:
dark matter candidates and their detection. I finally discuss some of the
limits of the $\Lambda$CDM model, with particular emphasis on the small scale
problems of the paradigm.
