A pre- $(n + 2)$ -angulated category which is not $(n + 2)$ -angulated

Jian He, Jing He, Panyue Zhou

We construct an explicit pre- $9$ -angulated category which is not $9$ -angulated, thereby giving a genuinely higher counterexample to the implication from pre- $(n + 2)$ -angulated to $(…

Auslander-Reiten (n+2)-angles and local finiteness

Jian He, Yu-Zhe Liu, Panyue Zhou

Let $C$ be an $(n + 2)$ -angulated category. Zhou proved that, when $n$ is odd, if the Auslander-Reiten $(n + 2)$ -angles generate the relations for the Grothendieck group of $\…
