Hilbert functions of double point schemes in P^2

Commutative Algebra 2011-09-19 v1

Abstract

We study the question of whether there is a minimum Hilbert functions for double point schemes whose support is ss points with the generic Hilbert functions. Previous work shows that the question has an affirmative answer for s9s \le 9 and for ss equal to a binomial coefficient number. In this paper, we give evidence in the case when ss equals to a binomial coefficient number plus 1, and give an affirmative answer to the question when s=11s = 11.
