Duality pairs and stable module categories
Abstract
Let be a commutative ring. We show that any complete duality pair gives rise to a theory of relative homological algebra, analogous to Gorenstein homological algebra. Indeed Gorenstein homological algebra over a commutative Noetherian ring of finite Krull dimension can be recovered from the duality pair where is the class of flat -modules and is the class of injective -modules. For a general , the AC-Gorenstein homological algebra of Bravo-Gillespie-Hovey is the one coming from the duality pair where is the class of level -modules and is class of absolutely clean -modules. Indeed we show here that the work of Bravo-Gillespie-Hovey can be extended to obtain similar abelian model structures on -Mod from any a complete duality pair . It applies in particular to the original duality pairs constructed by Holm-J{\o} rgensen.
