Algebraic complete integrability of an integrable system of Beauville
[Complète intégrabilité algébrique d’un système intégrable de Beauville]
Annales de l'Institut Fourier, Tome 58 (2008) no. 2, pp. 559-570.

Nous montrons que le système intégrable de Beauville sur un espace de dimension dix de modules de faisceaux sur une surface K3 construit par un espace de modules de faisceaux stables sur les cubiques de dimension trois est algébriquement complètement intégrable. Nous utilisons la construction d’O’Grady d’une résolution symplectique de l’espace des modules de faisceaux sur une surface K3.

We show that the Beauville’s integrable system on a ten dimensional moduli space of sheaves on a K3 surface constructed via a moduli space of stable sheaves on cubic threefolds is algebraically completely integrable, using O’Grady’s construction of a symplectic resolution of the moduli space of sheaves on a K3.
