Past talks

Speaker: Théophile Dolmaire
Title: Inelastic collapse of three particles in dimension $d\geq 2$
Title: Existence theory for a general class of stationary radiative transfer equations
The distribution of the temperature in a body where the heat is transmitted only by radiation can be studied using the radiative transfer equation (RTE). In this talk we consider the stationary RTE for absorption and scattering coefficients which can depend on both frequency and local temperature. The problem can be reformulated as an equivalent fixed-point equation for the temperature T. The main difficulty arises when we want to obtain compactness for the resulting non-linear problem involving exponentials of some integrals along straight lines. This requires a new compactness result for such operators. Moreover, when dealing with the full equation with both absorption/emission and scattering terms we have to combine the compactness result with the definition of suitable Green functions. This is joint work with Jin Woo Jang and Juan J.L. Velázquez.
