A possibility is considered that the observed neutrino oscillations are due to refraction effects on a very light scalar dark matter. Properties of the effective neutrino mass-squared responsible for the oscillation effects are studied. In particular, the dependence of the effective mass on state of medium: a cold gas of particles or a classical scalar field is explored. Cosmological...
