[Déformations naturelles des automorphismes symplectiques sur les variétés de type K3[n]]
Comptes Rendus. Mathématique, Tome 351 (2013) no. 13-14, pp. 561-564.

Dans cette étude, on démontre que tout groupe dʼordre fini des automorphismes symplectiques sur les variétés de type K3[n] sʼobtient comme déformation des automorphismes naturels provenant dʼune surface K3 si et seulement si il satisfait une certaine condition numérique.

In the present paper, we prove that finite symplectic groups of automorphisms of manifolds of K3[n] type can be obtained by deforming natural morphisms arising from K3 surfaces if and only if they satisfy a certain numerical condition.
