Relic Neutrino Asymmetries

Abstract

I review the topic of relic neutrino asymmetry generation through active-sterile neutrino and antineutrino oscillations in the early universe. Applications to (i) the suppression of sterile neutrino production, and (ii) the primordial Helium abundance are briefly presented.
