具有Auslander对偶复形的环

Rings with Auslander Dualizing Complexes

Amnon Yekutieli, James J. Zhang

摘要:

具有Auslander对偶复形的环是Auslander-Gorenstein环的推广。我们证明了Auslander-Gorenstein环的许多结果在更一般的情况下也成立。另一方面,我们给出了Auslander对偶复合物存在的准则,表明这些复合物经常发生。我们使用的最有力的工具是域上连通分次代数的局部对偶定理。滤子允许将结果转移到非分次代数。我们还证明了一些结果的范畴性质,最显着的刚性对偶复合体的功能性。

英文摘要:

A ring with an Auslander dualizing complex is a generalization of an Auslander-Gorenstein ring. We show that many results which hold for Auslander-Gorenstein rings also hold in the more general setting. On the other hand we give criteria for existence of Auslander dualizing complexes which show these occur quite frequently. The most powerful tool we use is the Local Duality Theorem for connected graded algebras over a field. Filtrations allow the transfer of results to non-graded algebras. We also prove some results of a categorical nature, most notably the functoriality of rigid dualizing complexes.
