Dimensions of triangulated categories via Koszul objects

Category Theory 2009-04-15 v3 Representation Theory

Abstract

Lower bounds for the dimension of a triangulated category are provided. These bounds are applied to stable derived categories of Artin algebras and of commutative complete intersection local rings. As a consequence, one obtains bounds for the representation dimensions of certain Artin algebras.
