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 …

The integral Hodge conjecture for two-dimensional Calabi–Yau categories
A Perry - Compositio Mathematica, 2022 - cambridge.org
We formulate a version of the integral Hodge conjecture for categories, prove the conjecture
for two-dimensional Calabi–Yau categories which are suitably deformation equivalent to the …

Moduli spaces of stable objects in Enriques categories
We study moduli spaces of stable objects in Enriques categories by exploiting their relation
to moduli spaces of stable objects in associated K3 categories. In particular, we settle the …

Derived categories of hearts on Kuznetsov components
We prove a general criterion that guarantees that an admissible subcategory KK of the
derived category of an abelian category is equivalent to the bounded derived category of the …

Kuznetsov's Fano threefold conjecture via K3 categories and enhanced group actions
A Bayer, A Perry - Journal für die reine und angewandte Mathematik …, 2023 - degruyter.com
We settle the last open case of Kuznetsov's conjecture on the derived categories of Fano
threefolds. Contrary to the original conjecture, we prove the Kuznetsov components of …

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 …

Stability conditions on Kuznetsov components of Gushel–Mukai threefolds and Serre functor
L Pertusi, E Robinett - Mathematische Nachrichten, 2023 - Wiley Online Library
We show that the stability conditions on the Kuznetsov component of a Gushel–Mukai
threefold, constructed by Bayer, Lahoz, Macrì and Stellari, are preserved by the Serre …
