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
To any 0-dimensional, reduced, degree s, projective scheme X we associate a set SX of sequences of s natural numbers; these sequences turn out to be a suitable permutations of a nondecreasing sequence (d1; : : : ; ds), which is in 1-1 correspondence with the ΓΏrst di erence X of the Hilbert function
