交换诺特环的倾斜、余倾斜和谱

Tilting, cotilting, and spectra of commutative noetherian rings

Lidia Angeleri Hügel, David Pospisil, Jan Stovicek, Jan Trlifaj

摘要:

我们分类的所有倾斜和cotilting类交换诺特环的下降序列的特殊化闭子集的Zagliki谱。从而,对有界投射维数的有限生成模的所有分解子范畴进行了分类。我们还将我们的结果与Hochster猜想的存在性的最大Cohen-Macaulay生成的模。

英文摘要:

We classify all tilting and cotilting classes over commutative noetherian rings in terms of descending sequences of specialization closed subsets of the Zariski spectrum. Consequently, all resolving subcategories of finitely generated modules of bounded projective dimension are classified. We also relate our results to Hochster's conjecture on the existence of finitely generated maximal Cohen-Macaulay modules.
