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 …

Purity and 2-Calabi-Yau categories

B Davison - arXiv preprint arXiv:2106.07692, 2021 - arxiv.org
For various 2-Calabi-Yau categories $\mathscr {C} $ for which the stack of objects

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 …

Some remarks on Fano three-folds of index two and stability conditions
