Let be a commutative noetherian ring. We prove that the class of modules of projective dimension bounded by is of finite type if and only if satisfies Serre’s condition . In particular, this answers positively a question of Bazzoni and Herbera in the specific setting of a Gorenstein ring. Applying similar techniques, we also show that the -dimensional version of the Govorov-Lazard Theorem holds if and only if satisfies the “almost” Serre condition .
