Ideal approximation in $n$ -angulated categories

Lingling Tan, Dingguo Wang, Tiwei Zhao

In this paper, we study ideal approximation theory associated to almost $n$ -exact structures in extension closed subcategories of $n$ -angulated categories. For $n = 3$ , an $n$ -angula…

Almost Split Triangles and Morphisms Determined by Objects in Extriangulated Categories

Tiwei Zhao, Lingling Tan, Zhaoyong Huang

Let $(C, E, s)$ be an Ext-finite, Krull-Schmidt and $k$ -linear extriangulated category with $k$ a commutative artinian ring. We define an additive subc…
