Conjecture de Hodge pour les produits des surfaces K3

Mardi 26 juin 2018 14:15-15:15 - Daniel Huybrechts - Univ. Bonn

Résumé : Shafarevich conjectured that every isogeny between K3 surfaces is algebraic. This is a special case of the Hodge conjecture for products of K3 surfaces and has been proved by Buskin.
In the talk, I shall explain a conceptual proof of the result relying on derived categories and motives of K3 surfaces.
