WebIn general, the Hilbert function will stabilize to a polynomial. This leads to the de nition of the Hilbert polynomial. Theorem 4. Let M = L 1 m=0 M m be a nitely-generated graded module over S= k[X 0;:::;X n], then there exists a polynomial p M(z) 2Q[z] such that h M(m) = p M(m) for m˛0. We call p M the Hilbert polynomial of M.
