摘要：

We identify fixed points in the renormalization group equations for neutrino mixing angles, which can be reached during the evolution for several mass patterns and give sin(2)2 theta(sol) = sin(2)2 theta(atm) sin(2)theta(3)/(sin(2)theta(atm)cos(2)theta(3) + sin(2)theta(3))(2), consistently with the present experimental information. Further experimental test of this relation is of crucial interest. Several interesting mass patterns show stability in the presence of fixed point solutions for the angles.
