Predictions for the Dirac CP violation phase in the neutrino mixing matrix

Using the fact that the neutrino mixing matrix U = (UeUv)-U-dagger , where U-e and U-v result from the diagonalization of the charged lepton and neutrino mass matrices, we analyze the predictions based on the sum rules which the Dirac phase delta present in U satisfies when U-v has a form dictated by, or associated with, discrete flavor symmetries and U-e has a "minimal" form (in terms of angles and phases it contains) that can provide the requisite corrections to U-v, so that the reactor, atmospheric and solar neutrino mixing angles theta(13), theta(23) and theta(12) have values compatible with the current data. $U_e$ has a ``minimal'' form (in terms of angles and phases it contains) that can provide the requisite corrections to $U_{ u}$, so that the reactor, atmospheric and solar neutrino mixing angles $ heta_{13}$, $ heta_{23}$ and $ heta_{12}$ have values compatible with the current data.
