AI总结:

本文研究了正则Noetherian代数堆上具有准凝聚上同调的复形导出范畴,证明其由单个完美复形生成,并在集中情况下为单个紧生成。

摘要:

我们证明,正则Noetherian代数堆上具有准有限对角的复形导出范畴由单个完美复形生成。在集中情况下,该范畴是单个紧生成的。证明中的关键成分包括沿再合拼接接生成体以及合适的滤子和代数堆的呈现。

英文摘要:

We show that the derived category of complexes with quasi-coherent cohomology on a regular Noetherian algebraic stack with quasi-finite diagonal is generated by a single perfect complex. In the concentrated case, the category is singly compactly generated. Key ingredients in the proofs include gluing generators along recollement and the use of suitable filtrations and presentations of the algebraic stack.
