Separators of Fat Points in Multiprojective Spaces

چکیده

Let Z be a set of fat points in a multiprojective space Pn × · · · × Pn . We introduce definitions for the separator of a fat point and the degree of a fat point in this context, and we study some of their properties. Our definition has been picked so that when we specialize to the cases: (a) Z is a reduced set of points in Pn , (b) Z is a set of fat points in Pn, or (c) Z is a reduced set of points in Pn × · · · × Pn , we are consistent with previous definitions and results of Orecchia, Marino, and the authors.

Separators of Points in a Multiprojective Space

In this note we develop some of the properties of separators of points in a multiprojective space. In particular, we prove multigraded analogs of results of Geramita, Maroscia, and Roberts relating the Hilbert function of X and X \ {P} via the degree of a separator, and Abrescia, Bazzotti, and Marino relating the degree of a separator to shifts in the minimal multigraded free resolution of the ...

Cohomological Characterization of Vector Bundles on Multiprojective Spaces

We show that Horrock’s criterion for the splitting of vector bundles on Pn can be extended to vector bundles on multiprojective spaces and to smooth projective varieties with the weak CM property (see Definition 3.11). As a main tool we use the theory of n-blocks and Beilinson’s type spectral sequences. Cohomological characterizations of vector bundles are also showed.

Multigraded Regularity: Syzygies and Fat Points Jessica Sidman and Adam Van Tuyl

The Castelnuovo-Mumford regularity of a graded ring is an important invariant in computational commutative algebra, and there is increasing interest in multigraded generalizations. We study connections between two recent definitions of multigraded regularity with a view towards a better understanding of the multigraded Hilbert function of fat point schemes in P n1 × · · · × P k . Introduction L...

Acm Sets of Points in Multiprojective Space

If X is a finite set of points in a multiprojective space P1 × · · · × Pr with r ≥ 2, then X may or may not be arithmetically Cohen-Macaulay (ACM). For sets of points in P × P there are several classifications of the ACM sets of points. In this paper we investigate the natural generalizations of these classifications to an arbitrary multiprojective space. We show that each classification for AC...

Regularity and Cohomological Splitting Conditions for Vector Bundles on Multiprojectives Spaces

Here we give a definition of regularity on multiprojective spaces which is different from the definitions of Hoffmann-Wang and Costa-Miró Roig. By using this notion we prove some splitting criteria for vector bundles.
