Abstract

The goal of the paper is to build particular three codimensional arithmetically Cohen-Macaulay subschemes of P^r , partial Gorenstein schemes, whose graded Betti numbers can be easily computed in terms of their combinatorial support. This approach permits to realize many Betti sequences of schemes with the same Hilbert function.
