Abstract
The role of a resonant nu(e)-nu(s) oscillation is discussed for the ev ent of a supernova explosion. It is concluded that a significant nu(e) -nu(s) mixing may hinder the ability of the supernova to explode. It m ay also cool the proto-neutron star too quickly with respect to the ob served cooling time of several seconds. The constraints on the nu(e)-n u(s) mixing parameters based on the above arguments are calculated.
