Abstract
Within the hypothesis that the Majorana mass of ordinary neutrinos dominates the rate of neutrinoless double beta decay, the predictions from neutrino oscillations are updated. These are then compared with the results from cosmology and from the neutrinoless double beta decay searches. In the discussion of the nuclear uncertainties, particular attention is paid to the impact of the quenching of the axial vector coupling constant in the nuclear medium. Finally, considering possible implications of the knowledge on neutrino masses from cosmology, a possible access to an experimental determination of the Majorana phases is discussed.
