Abstract
In the derived category of modules over a commutative noetherian ring a complex is said to generate a complex if the latter can be obtained from the former by taking summands and finitely many cones. The number of cones required in this process is the generation time of . In this paper we present some local to global type results for computing this invariant, and discuss applications.
