弱整体维数至多为1的环的Smashing局部化

Smashing localizations of rings of weak global dimension at most one

Silvana Bazzoni, Jan Stovicek

摘要:

本文证明了对于弱整体维数至多为1的环R,在其导出范畴的粉碎子范畴与R中的同调满态的等价类之间存在一个双射。此外,如果R是交换的,我们证明了紧生成的局部化子范畴正好对应于平坦满射。我们还对任意赋值整环的导出范畴的粉碎局部化进行了分类,并对任意弱整体维数至多为1的交换环给出了望远镜猜想(TC)的一个简单判据.因此,我们证明了TC对任何交换von Neumann正则环R都成立,并且对强离散的Prüfer整环也成立.

英文摘要:

We show for a ring R of weak global dimension at most one that there is a bijection between the smashing subcategories of its derived category and the equivalence classes of homological epimorphisms starting in R. If, moreover, R is commutative, we prove that the compactly generated localizing subcategories correspond precisely to flat epimorphisms. We also classify smashing localizations of the derived category of any valuation domain, and provide an easy criterion for the Telescope Conjecture (TC) for any commutative ring of weak global dimension at most one. As a consequence, we show that the TC holds for any commutative von Neumann regular ring R, and it holds precisely for those Prüfer domains which are strongly discrete.
