Auslander公式:变化和应用

Auslander's Formula: Variations and Applications

Javad Asadollahi, Najmeh Asadollahi, Rasool Hafezi, Razieh Vahed

摘要:

根据Auslander的公式,研究阿贝尔范畴${\mathcal{C}}$的一种方法是研究同调性质比${\mathcal{C}}$好的${\rm mod}\mbox{-}{\mathcal{C}}$,然后将结果转化回${\mathcal{C}}$ .最近Krause给出了这个公式的一个衍生版本,从而更新了这个主题。本文详细研究了Auslander公式的各种版本,包括对所有模的版本和对无界导出范畴的版本。我们应用它们来包括一些关于三角范畴的重元素的结果。

英文摘要:

According to the Auslander's formula one way of studying an abelian category ${\mathcal{C}}$ is to study ${\rm mod}\mbox{-}{\mathcal{C}}$, that has nicer homological properties than ${\mathcal{C}}$, and then translate the results back to ${\mathcal{C}}$. Recently Krause gave a derived version of this formula and thus renewed the subject. This paper contains a detailed study of various versions of Auslander formula including the versions for all modules and for unbounded derived categories. We apply them to include some results concerning recollements of triangulated categories.
