Abstract

Let HX be the trigraded Hilbert function of a set X of reduced points in $\mathbb{P}$ 1 × $\mathbb{P}$ 1 × $\mathbb{P}$ 1. We show how to extract some geometric information about X from HX . This paper generalises a similar result of Giuffrida, Maggioni and Ragusa about sets of points in $\mathbb{P}$ 1 × $\mathbb{P}$ 1.
