| Aug 27, 2010 at 19:50 | comment | added | Jesse Burke | In Schouten's work he shows that the net generated by the cylic modules of the form A/p, for p singular, is the entire category of finitely generated modules. A net lives in the abelian category of modules, but it's easy to see using Schouten's work that the objects A/p, for p singular, generate the bounded finite derived category. Moreover they're compact by work of Krause. However the set of singular primes set is not finite usually. Roquier have shown that a compact generator exists for the finite bounded derived category of most commutative rings; I believe all k-algebras of finite type. | |
