Abstract: | A brief review for particle physicists on the cosmological impact of neutrinos and on restrictions on neutrino properties
from cosmology is given. The paper includes a discussion of upper bounds on neutrino mass and possible ways to relax them,
methods to observe the cosmic-neutrino background, bounds on the cosmological lepton asymmetry which are strongly improved
by neutrino oscillations, cosmological effects of breaking of the spin-statistics theorem for neutrinos, bounds on mixing
parameters of active and possible sterile neutrinos with account of active-neutrino oscillations, bounds on right-handed currents
and neutrino magnetic moments, and some more.
