Nous considérons l'équation de Burgers avec diffusion fractionnelle dans ${ℝ}^N$. Nous montrons l'existence de solutions globales regulières pour toute donnée initiale dans $L^2\left({ℝ}^N\right)$, en utilisant une version parabolique de la méthode de De Giorgi introduite par Caffarelli et Vasseur.

We consider the fractional Burgers' equation on ${ℝ}^N$ with the critical dissipation term. We follow the parabolic De-Giorgi's method of Caffarelli and Vasseur and show existence of smooth solutions given any initial datum in $L^2\left({ℝ}^N\right)$.
