Abstract

We introduce a general method to induce Bridgeland stability conditions on semiorthogonal components of triangulated categories. In particular, we prove the existence of Bridgeland stability conditions on the Kuznetsov component of the derived category of Fano threefolds and of cubic fourfolds. As an application, in the appendix, written jointly with Xiaolei Zhao, we give a variant of the proof of the Torelli theorem for cubic fourfolds by Huybrechts and Rennemo.
Nous introduisons une méthode générale pour induire des conditions de stabilité de Bridgeland sur des composantes semi-orthogonales des catégories triangulées. En particulier, nous prouvons l'existence de conditions de stabilité de Bridgeland sur la composante de Kuznetsov de la catégorie dérivée de 3-variétés de Fano, ainsi que de 4-variétés cubiques. Comme application, dans l'annexe, écrite conjointement avec Xiaolei Zhao, nous donnons une variante de la preuve de Huybrechts et Rennemo du théorème de Torelli pour les 4-variétés cubiques.
