N2 - We obtain model independent relations among neutrino masses and leptogenesis parameters. We find exact relations that involve the CP asymmetries Nα, the washout parameters α and θαβ, and the neutrino masses mi and Mα, as well as powerful inequalities that involve just α and mi. We prove that the Yukawa interactions of at least two of the heavy singlet neutrinos are in the strong washout region (α 10-3eV).
