From finite to infinite length modules over tame hereditary algebras
Lidia Angeleri Hügel, Andrew Hubery, Henning Krause
A self-contained introduction to infinite dimensional representations over a tame hereditary algebra is provided, assuming a basic knowledge of the category of finite dimensional r…

The invariance of the Auslander-Reiten Formula for hereditary algebras
Andrew Hubery
We show that the Auslander-Reiten Formula for a finite dimensional hereditary algebra is invariant under the Auslander-Reiten translate.

On the global dimension and Koszul property for preprojective algebras
Andrew Hubery
We study preprojective algebras associated to either finite dimensional hereditary algebras, or locally finite hereditary tensor algebras, and in particular show that they have glo…
