最大$τ_d$ -刚性对

Maximal $τ_d$-rigid pairs

Karin M. Jacobsen, Peter Jorgensen

摘要:

设$\mathscr T$是一个$2$ -Calabi--Yau三角范畴,$T$是一个簇倾斜对象,它具有自同态代数$Γ$ .考虑函子$\mathscr T( T,- ) : \mathscr T \rightarrow \mod Γ$。它诱导了一个从簇倾斜对象的同构类到支撑$τ$ -倾斜对的同构类的双射。这是由于足立,Iyama和Reiten。$( d+2 )$ -角范畴的概念是三角范畴的高级类比。基于最大$τ_d$刚性对的概念,我们给出了上述结果的更高的模拟。

英文摘要:

Let $\mathscr T$ be a $2$-Calabi--Yau triangulated category, $T$ a cluster tilting object with endomorphism algebra $Γ$. Consider the functor $\mathscr T( T,- ) : \mathscr T \rightarrow \mod Γ$. It induces a bijection from the isomorphism classes of cluster tilting objects to the isomorphism classes of support $τ$-tilting pairs. This is due to Adachi, Iyama, and Reiten. The notion of $( d+2 )$-angulated categories is a higher analogue of triangulated categories. We show a higher analogue of the above result, based on the notion of maximal $τ_d$-rigid pairs.
