Hilbert functions of irreducible arithmetically Gorenstein schemes
Nero Budur, Marta Casanellas, Elisa Gorla
In this paper we compute the Hilbert functions of irreducible (or smooth) and reduced arithmetically Gorenstein schemes that are twisted anti-canonical divisors on arithmetically C…

Gorenstein Liaison and ACM Sheaves
Marta Casanellas, Elena Drozd, Robin Hartshorne
We study Gorenstein liaison of codimension two subschemes of an arithmetically Gorenstein scheme X. Our main result is a criterion for two such subschemes to be in the same Gorenst…

Gorenstein Biliaison and ACM Sheaves
Marta Casanellas, Robin Hartshorne
Let be a normal arithmetically Gorenstein scheme in . We give a criterion for all codimension two ACM subschemes of to be in the same Gorenstein biliaison cl…
