A Note on the Cauchy problem for the 2D generalized Zakharov–Kuznetsov equations
[Une Note sur le problème de Cauchy pour les équations de Zakharov–Kuznetsov 2D généralisées]
Comptes Rendus. Mathématique, Tome 350 (2012) no. 9-10, pp. 499-503.

Nous étudions dans cette Note les équations de Zakharov–Kuznetsov 2D généralisées tu+Δxu+ukxu=0 pour k2. Il est établi que le problème de Cauchy peut être résolu par une méthode itérative dans les espaces de Sobolev Hs(R2) pour s>1/4 si k=2, s>5/12 si k=3 et s>12/k si k4.

In this Note we study the generalized 2D Zakharov–Kuznetsov equations tu+Δxu+ukxu=0 for k2. By an iterative method we prove the local well-posedness of these equations in the Sobolev spaces Hs(R2) for s>1/4 if k=2, s>5/12 if k=3 and s>12/k if k4.
