戴环空间上的扭曲复形作为完全复形的dg-增强

Twisted complexes on a ringed space as a dg-enhancement of perfect complexes

Zhaoting Wei

摘要:

本文研究了戴环空间上的扭复形,证明了它给出了该空间上完全复形的导出范畴的一个新的dg-加强。扭曲复形是局部定义的层与同伦粘合数据的集合。本文构造了一个从扭曲复形到完全复形的dg-函子,证明了它是一个dg-增强。这种新的增强具有完全几何的优点,它直接来自完美复形的定义。此外,我们将讨论一些应用和进一步的主题周围扭曲复杂。

英文摘要:

In this paper we study twisted complexes on a ringed space and prove that it gives a new dg-enhancement of the derived category of perfect complexes on that space. A twisted complex is a collection of locally defined sheaves together with the homotopic gluing data. In this paper we construct a dg-functor from twisted complexes to perfect complexes, which turns out to be a dg-enhancement. This new enhancement has the advantage of being completely geometric and it comes directly from the definition of perfect complex . In addition we will talk about some applications and further topics around twisted complexes.
