support of embedded points in a curve
Let $C \subset \mathbb{P}^n$ be an one dimensional scheme. Suppose that $C$ decomposes as the union of a Cohen Macaulay reduced curve $\tilde{C}$ (in particular $\tilde{C}$ does not have embedded poin …

calculating the Hilbert polynomial of a scheme given its primary decomposition
Given a scheme $X$ in $\mathbb{P}^n$, let $I_X$ be its, saturated, associated ideal. Suppose that a primary decomposition of this ideal is given by
$$
I_X =I_1 \cap \ldots \cap I_2
$$
