Interaction of neutrinos and gravitons with plasmas in the universe

The nonlinear propagation of neutrinos and gravitons in a plasma has been c onsidered within the framework of the general relativity. A set of governin g equations for plasmas as well as for neutrinos and gravitational waves ha s been developed. The results should be useful for formulating the nonlinea r coupling scenarios between high-energy neutrinos, intense radiation/plasm ons, and gravitons, which should help to understand the combined influence of the weak nuclear, strong electromagnetic, and gravitational forces in as trophysical settings as well as in the early universe.
