A criterion for sequential Cohen-Macaulayness
Giulio Caviglia, Alessandro De Stefani
The purpose of this note is to show that a finitely generated graded module over , a field, is sequentially Cohen-Macaulay if and only if its arithmeti…
Ladder determinantal varieties and their symbolic blowups
Alessandro De Stefani, Jonathan Montaño, Luis Núñez-Betancourt +2
In this article we show that the symbolic Rees algebra of a mixed ladder determinantal ideal is strongly -regular. Furthermore, we prove that the symbolic associated graded alge…
On the notion of sequentially Cohen-Macaulay modules
Giulio Caviglia, Alessandro De Stefani, Enrico Sbarra +1
In this survey paper we first present the main properties of sequentially Cohen-Macaulay modules. Some basic examples are provided to help the reader with quickly getting acquainte…
On the rate of generic Gorenstein -algebras
Mats Boij, Emanuela De Negri, Alessandro De Stefani +1
The rate of a standard graded -algebra is a measure of the growth of the shifts in a minimal free resolution of as an -module. In particular has rate one if and o…
