dc.description.abstract	We propose an SO(10) scheme where \neu masses can simultaneously explain the solar and atmospheric neutrino deficits, together with a hot dark matter component. In our scheme the νe, νμ, and ντ are approximately degenerate with a mass of about 2 eV, which can lead to an observable neutrinoless double beta decay rate. The model is based on a realization of the seesaw mechanism in which the main contribution to the light \neu masses is universal, due to a suitable SU(2) horizontal symmetry, while the splittings between \ne and \nm explain the solar \neu deficit and that between \nm and \nt explain the atmospheric \neu anomaly.
