If you have a question about this talk, please contact Alessio Martini. The Landau-Lifshitz equation describes the macroscopical dynamics of the magnetization in a ferromagnetic material. In the physical literature there are formal arguments showing that, depending on the anisotropy of the materials, the Landau-Lifshitz equation can be approximated by the cubic nonlinear Schrodinger equation or by the Sine-Gordon equation. In this talk, we rigurosly establish these aproximations, by using well-tailored energy estimates with good symmetrization properties, that lead to estimates of the differences in Sobolev norms.
