In this chapter we develop the basic properties of sets of points in (Formula Presented). We begin by describing the bihomogeneous ideal I(P) associated with a point (Formula Presented). We also discuss the connection between sets of points X in (Formula Presented) and special configurations of lines in (Formula Presented). Because (Formula Presented) is isomorphic to the ruled quadric surface in (Formula Presented), we can visualize a collection of points X as sitting within a grid of lines. After describing how to represent a set of points X in (Formula Presented), we extract some combinatorial information from this representation.

Abstract
In this chapter we develop the basic properties of sets of points in (Formula Presented). We begin by describing the bihomogeneous ideal I(P) associated with a point (Formula Presented). We also discuss the connection between sets of points X in (Formula Presented) and special configurations of lines in (Formula Presented). Because (Formula Presented) is isomorphic to the ruled quadric surface in (Formula Presented), we can visualize a collection of points X as sitting within a grid of lines. After describing how to represent a set of points X in (Formula Presented), we extract some combinatorial information from this representation.File in questo prodotto:
