Effect of fluctuations on cosmologically significant neutrino parameter space constraints obtained from a type II Supernova

I will start with a review of neutrino oscillations and the MSW effect and present numerical results that illustrate these phenomenon. I will than argue that the 'Hot Bubble' environment in type II supernovae is the most plausible site for r-process nucleosynthesis. Given this, it is possible to obtain constraints in the neutrino parameter space under certain assumptions. I will present numerical results of such constraints for cosmologically significant neutrinos. Finally i will present a formalism for studying the effects of density fluctuations on the propagation of neutrinos and present numerical results on the effects of such fluctuations on the constraint space obtained earlier.
