| Résumé: |
MB - Unified approach to fluid approximation of linear kinetic equations with heavy tails - |
| Description: |
Émeric Bouinanomalousit is a governed
by a fractional diffusion equation. Lebeau and Puel proved
last year the first similar result for Fokker-Planck operator,
in dimension 1 and assuming that the equilibrium distribution
has finite mass. Fournier and Tardif gave an alternative
probabilistic proof, more general (covering any dimension and
infinite-mass equilibrium distribution) but non-constructive.
We present a unified elementary approach, fully quantitative,
that covers all previous cases as well as new ones. This is a
joint work with Clément Mouhot (University of Cambridge). |
