  As was shown previously, oscillations of massless neutrinos may be due to the
splitting of multiply degenerate Fermi points. In this Letter, we give the
details and propose a three-flavor model of Fermi point splittings and neutrino
mixings with only two free parameters. The model may explain recent
experimental results from the K2K and KamLAND collaborations. There is also
rough agreement with the data on atmospheric neutrinos (SuperK) and solar
neutrinos (SNO), but further analysis is required. Most importantly, the Ansatz
allows for relatively strong T-violating (CP-nonconserving) effects in the
neutrino sector.
