Generating the bounded derived category and perfect ghosts

Category Theory 2012-07-10 v2 Algebraic Geometry Representation Theory

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.
