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 Deligne-Simpson Problem
William Crawley-Boevey, Andrew Hubery
Given k similarity classes of invertible matrices, the Deligne-Simpson problem asks to determine whether or not one can find matrices in these classes whose product is the identity…
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…
