支持$τ_2$ -倾斜和2-扭转对

Support $τ_2$-tilting and 2-torsion pairs

Jordan McMahon

摘要:

$τ$ -倾斜模的理论是由Adachi-Iyama-Reiten提出的,其主要结果之一是支撑$τ$ -倾斜模与挠类之间的一个双射.我们能够概括这一结果的背景下,更高的Auslander-Reiten理论的Iyama。对于具有2-簇倾斜子范畴$\mathcal{C}\subseteq\mathrm{mod}A$的有限维代数$A$,我们能够找到支撑$τ_2$ -倾斜$A$ -模与$\mathcal{C}$中满足附加函子有限性条件的扭对之间的对应关系.

英文摘要:

The theory of $τ$-tilting was introduced by Adachi--Iyama--Reiten; one of the main results is a bijection between support $τ$-tilting modules and torsion classes. We are able to generalise this result in the context of the higher Auslander--Reiten theory of Iyama. For a finite-dimensional algebra $A$ with 2-cluster-tilting subcategory $\mathcal{C}\subseteq\mathrm{mod}A$, we are able to find a correspondence between support $τ_2$-tilting $A$-modules and torsion pairs in $\mathcal{C}$ satisfying an additional functorial finiteness condition.
