On components that contain Heller lattices: an example

摘要: Auslander-Reiten theory for finite dimensional algebras is well-established. There is also Auslander-Reiten theory for orders, but it seems no references which define AR-quivers for orders in non semi-simple algebras and study their shapes. I will explain how to construct almost split sequences for self-injective orders and introduce Heller lattices. Then, we show, in a simple example, the shape of components of stable AR-quiver that contain Heller lattices.
