Abstract (VO)
Résumé

In the present paper, we prove that finite symplectic groups of automorphisms of manifolds of $K 3^{[n]}$ type can be obtained by deforming natural morphisms arising from K3 surfaces if and only if they satisfy a certain numerical condition.

Dans cette étude, on démontre que tout groupe dʼordre fini des automorphismes symplectiques sur les variétés de type $K 3^{[n]}$ sʼobtient comme déformation des automorphismes naturels provenant dʼune surface K3 si et seulement si il satisfait une certaine condition numérique.
