Stability conditions in families
We develop a theory of Bridgeland stability conditions and moduli spaces of semistable
objects for a family of varieties. Our approach is based on and generalizes previous work by …

Stability conditions on Kuznetsov components
We introduce a general method to induce Bridgeland stability conditions on semiorthogonal
components of triangulated categories. In particular, we prove the existence of Bridgeland …

Categorical Torelli theorems: results and open problems
L Pertusi, P Stellari - Rendiconti del Circolo Matematico di Palermo Series …, 2023 - Springer
We survey some recent results concerning the so called Categorical Torelli problem. This is
to say how one can reconstruct a smooth projective variety up to isomorphism, by using the …

Some remarks on Fano three-folds of index two and stability conditions
L Pertusi, S Yang - International Mathematics Research Notices, 2022 - academic.oup.com
We prove that ideal sheaves of lines in a Fano three-fold of Picard rank one and index two
are stable objects in the Kuznetsov component, with respect to the stability conditions …

Elliptic quintics on cubic fourfolds, O'Grady 10, and Lagrangian fibrations
For a smooth cubic fourfold Y, we study the moduli space M of semistable objects of Mukai
