Ideal classes of three dimensional Artin-Schelter regular algebras
K. De Naeghel, M. Van den Bergh
We determine the possible Hilbert functions of graded rank one torsion free modules over three dimensional Artin-Schelter regular algebras. It turns out that, as in the commutative…

Ideal classes of three dimensional Sklyanin algebras
K. De Naeghel, M. Van den Bergh
In this paper we classify graded reflexive ideals, up to isomorphism and shift, in certain three dimensional Artin-Schelter regular algebras. This classification is similar to the…
