In the scenario with degenerate neutrino masses at tree-level,
we show how threshold corrections with either non-trivial or trivial
mixing at tree-level have the power to generate the observed
deviations from a degenerate spectrum. Moreover, it is possible to
also generate the mixing fully radiatively when there is trivial
mixing at tree-level.
We give a brief overview over the topic and discuss the outcome of
threshold corrections for degenerate neutrino masses in a
supersymmetric model. A detailed description can be found
in TTP14-034.
