摘要：

The singular (det M = 0) Majorana neutrino mass submatrix, advocated by Glashow, is given a minimal U(1)Lepton + Axial realization, Stemming from the Fritzsch-like universality of the Dirac mass matrix, a detailed Dirac/Majorana interplay is derived. The identification nu(Simpson) = nu-tau, cannot tolerate an arbitrarily small m-nu-e/m-nu-mu-mass ratio. The mass hierarchy m-nu-tau << m-tau is correlated with m(e) << m-tau. The solar neutrino mass scale m(MSW) less-than-or-equal-to m-mu-2/M (rather than = m-nu-tau-2/M) points towards M less-than-or-equal-to 10(10) GeV (the corresponding nu-tau-lifetime less-than-or-equal-to 10(-3) (M/m(W)2S), thus suggesting a possible link with axion physics.
