Postulation of general quartuple fat point schemes in P³
Ballico, Edoardo · Brambilla, Maria Chiara
Original · EN
We study the postulation of a general union Y of double, triple, and quartuple points of P³. We prove that Y has the expected postulation in degree d≥ 41, using the Horace differential lemma. We also discuss the cases of low degree with the aid of computer algebra.
