On présente des résultats permettant de mieux comprendre la structure du noyau de collision de Landau original (celui correspondant aux collisions entre particules chargées dans un plasma). À partir d’une estimation de la production d’entropie du noyau, on obtient des résultats pour l’équation de Landau homogène avec potentiel coulombien, qui concernent la régularité et le comportement asymptotique lorsque |v|→+∞.
