环的$Q$形导出范畴

The $Q$-shaped derived category of a ring

Henrik Holm, Peter Jorgensen

摘要:

对于任何环$A$和一个小的,预加的,Hom-finite,局部有界的范畴$Q$,有一个Serre函子,并满足(强)收缩性质,我们证明了从$Q$到(左)$A$ -模范畴的加函子范畴具有投射和内射模型结构。这些模型结构具有相同的平凡对象和弱等价,在大多数情况下,可以自然地用本文引入的某些(上)同调函子来刻画。被三角化的相关同伦范畴称为$A$的$Q$形导出范畴. $A$的通常的导出范畴就是一个例子;更一般的例子是把$Q$当作一个适当好的稳定平移范畴的网格范畴。本文建立在,并概括了,伊诺克,埃斯特拉达和加西亚-罗萨斯和戴尔'安布罗吉奥,史蒂文森和斯托维切克的作品。

英文摘要:

For any ring $A$ and a small, preadditive, Hom-finite, and locally bounded category $Q$ that has a Serre functor and satisfies the (strong) retraction property, we show that the category of additive functors from $Q$ to the category of (left) $A$-modules has a projective and an injective model structure. These model structures have the same trivial objects and weak equivalences, which in most cases can be naturally characterized in terms of certain (co)homology functors introduced in this paper. The associated homotopy category, which is triangulated, is called the $Q$-shaped derived category of $A$. The usual derived category of $A$ is one example; more general examples arise by taking $Q$ to be the mesh category of a suitably nice stable translation quiver. This paper builds upon, and generalizes, works of Enochs, Estrada, and Garcia-Rozas and of Dell'Ambrogio, Stevenson, and Stovicek.
