Combinatorial Restrictions on the Tree Class of the Auslander-Reiten Quiver of a Triangulated Category

Kosmas Diveris, Marju Purin, Peter Webb

We show that if a connected, Hom-finite, Krull-Schmidt triangulated category has an Auslander-Reiten quiver component with Dynkin tree class then the category has Auslander-Reiten…
