Résumé After
a
short
introduction
on what is known
and not known in neutrino physics, we will review the role played by
neutrinos in the evolution of cosmological background quantitites and
perturbations. We will pay a particular attention to the impact of
massive neutrino free-streaming on the linear growth factor during dark
matter and dark energy domination. We will show how future observations
- including Planck - can probe these effects. The end of the course
will be devoted to a brief dicussion of non-standard neutrinos
(sterile, coupled, etc.), and to the important question of including
massive neutrinos in predictions for the non-linear matter power
spectrum (with N-body simulations or semi-analytic methods).
