The main result, Theorem 1, provides an algorithm for determining the minimal free resolution of fat point subschemes of P 2 involving up to eight general points of arbitrary multiplicities. The resolutions obtained hold for any algebraically closed field, independent of the characteristic. The algo

β¦ Synopsis
In this paper we determine the Hilbert function and the minimal system of generators of r + 1 β€ n + 1 general fat points of n . Furthermore, by looking at the minimal system of generators we can show that the ideal associated to two fat points in n or the ideal associated to r + 1 β€ n general fat points, all with the same multiplicities, is a splittable ideal, and this is the first step in constructing a minimal resolution.

Let X be the surface obtained by blowing up general points p 1 p n of the projective plane over an algebraically closed ground field k, and let L be the pullback to X of a line on the plane. If C is a rational curve on X with C β’ L = d, then for every t there is a natural map C C t β X X L β C C t +
We address the problem of computing ideals of polynomials which vanish at a finite set of points. In particular we develop a modular Buchberger-MΓΆller algorithm, best suited for the computation over Q, and study its complexity; then we describe a variant for the computation of ideals of projective p
In this paper we find an algorithm which computes the Hilbert function of schemes Z of ''fat points'' in β«ήβ¬ 3 whose support lies on a rational normal cubic curve C. The algorithm shows that the maximality of the Hilbert function in degree Ε½ t is related to the existence of fixed curves either C its
In this paper we determine a new upper bound for the regularity index of fat points of \(P^{2}\), without requiring any geometric condition on the points. This bound is intermediate between Segre's bound, that holds for points in the general position, and the more general bound, that is attained whe
