Noether格式的稳定导出范畴

The stable derived category of a noetherian scheme

Henning Krause

摘要:

对于Noether格式,我们引入了它的无界稳定导出范畴。这导致了一个复元,它反映了从相干层的有界导出范畴到完全复形的子范畴的商模的通路。一些应用包括在内,例如模拟最大的科恩-麦考利近似,泰特上同调的建设,和经典的Grothendieck对偶的延伸。此外,还指出了稳定导出范畴在模表示理论中的相关性。

英文摘要:

For a noetherian scheme, we introduce its unbounded stable derived category. This leads to a recollement which reflects the passage from the bounded derived category of coherent sheaves to the quotient modulo the subcategory of perfect complexes. Some applications are included, for instance an analogue of maximal Cohen-Macaulay approximations, a construction of Tate cohomology, and an extension of the classical Grothendieck duality. In addition, the relevance of the stable derived category in modular representation theory is indicated.
