Colloquium Antoine Mellet University of Maryland Title: Anomalous diffusion phenomena: A kinetic approach Abstract: The derivation of diffusion or drift-diffusion equations from transport equations (such as Vlasov-Fokker-Planck or Boltzmann equations) is a classical problem. In this talk, we will discuss situations in which the usual derivation fails because the mean squared displacement of a particle does not grow linearly with time. We will show that such "anomalous diffusion" regimes typically lead to fractional diffusion equations. We will present in particular an application of this approach to the description of anomalous energy transport in FPU chains.
