题目：Pre-(n+2)-angulated categories

时间：2023年12月27日下午4:00 -- 5:00

报告地点：城关校区理工楼631

摘要：In this talk, we introduce the notion of a pre-(n+2)-angulated category as a higher dimensional analogue of a pre-triangulated category defined by Beligiannis-Reiten.We first show that the idempotent completion of a pre-(n+2)-angulated category admits a unique pre-(n+2)-angulated structure. Let (C,\Sigma^n,\Theta) be an (n+2)-angulated category and X be a strongly functorially finite subcategory of C.We then show that the quotient category C/X is a pre-(n+2)-angulated category.These results allow to construct several examples of pre-(n+2)-angulated categories.Moreover, we also give a necessary and sufficient condition for the quotient C/X to be an (n+2)-angulated category.
