摘要

我们证明了2n-Calabi-Yau (n + 2)-角范畴中Oppermann-Thomas簇倾斜对象的自同态代数上的一个广义倾斜模提升到该范畴中的一个相对簇倾斜对象。作为一种应用，这推广了Fu和Liu最近关于三角分类的工作。

Lifting to relative cluster tilting objects in $2n$-Calabi–Yau $(n+2)$-angulated categories

We show that a generalized tilting module over the endomorphism algebra of an Oppermann–Thomas cluster tilting object in a 2n-Calabi–Yau (n + 2)-angulated category lifts to a relative cluster tilting object in this category. As an application, this generalizes a recent work of Fu and Liu for triangulated categories.
