Query: CP Violations in Lepton Number Violation Processes and Neutrino
  Oscillations   We examine the constraints on the MNS lepton mixing matrix from the present
and future experimental data of the neutrino oscillation and lepton number
violation processes. We introduce a graphical representation of the CP
violation phases which appear in the lepton number violation processes such as
neutrinoless double beta decay, the $\mu^--e^+$ conversion, and the K decay,
$K^-\to\pi^+\mu^-\mu^-.$ Using this graphical representation, we derive the
constraints on the CP violation phases in the lepton sector.
