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

In this paper we determine the Hilbert function and the minimal system of generators of r + 1 โค 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 โค n general fat po
Projective resolutions of modules over a ring R are constructed starting from appropriate projective resolutions over a ring Q mapping to R. It is shown that such resolutions may be chosen to be minimal in codimension F 2, but not in codimension 3. This is used to obtain minimal resolutions for esse
