Abstract
The lepton number violating interactions generated by the light Majora na neutrinos can erase the primordial baryon asymmetry of the universe during the electroweak phase transition. The Majorana masses of the l eft-handed neutrinos are constrained to avoid this problem. These cons traints do not depend on the (B - L) symmetry breaking mechanism.
