Streszczenie
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.
