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 FokkerPlanck 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 infinitemass equilibrium distribution) but nonconstructive. 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).
