Abstract
We describe a geometric picture for the pattern of fermion masses of t he three generations which is invariant with respect to the renormaliz ation group below the electroweak scale. Moreover, we predict the uppe r limit for the ratio between the Dirac masses of the mu and tau neutr inos, (m(nu mu)/m(nu tau)) less than or equal to (9.6 +/- 0.6) x 10(-3 ).
