      Time splitting for nonlinear Schrödinger equations: Strichartz estimates and consequences 55m

      Strichartz estimates have allowed spectacular progress in the analytical
      study of nonlinear dispersive equations such as nonlinear Schrödinger
      equations. We show two consequences regarding error estimates for time
      splitting method: a global in time error estimate, obtained with Chunmei
      Su, and low regularity error estimates in the presence of an harmonic
      potential, using in addition Weyl-Hörmander pseudodifferential calculus.

      Generalised UGK and UGKWP Scheme in the Diffusive Limit 55m

      The unified gas kinetic scheme (UGKS) was initially designed to address
      multiscale challenges in rarefied gas dynamics and then extended to
      radiative transfert theory, as described by BGK like relaxation models.
      In this talk, we extend its application to linear kinetic models with
      non isotropic scattering collision operators, as well as Fokker-Planck
      models . These problems typically exhibit a fully diffusive nature in
      the optically thick limit (corresponding to a small Knudsen number). It
      still leads to an asymptotic preserving (AP) property not only in this
      diffusive regime but also in the free transport limit. A series of
      numerical experiments confirm the effectiveness of the approach.
