Generating the bounded derived category and perfect ghosts
arXiv:1006.3568 · doi:10.1112/blms/bdr093
Abstract
We show, for a wide class of abelian categories relevant in representation theory and algebraic geometry, that the bounded derived categories have no non-trivial strongly finitely generated thick subcategories containing all perfect complexes. In order to do so we prove a strong converse of the Ghost Lemma for bounded derived categories.
