"Closed Embeddings and Ideal Sheaves"

This week we will use our intuitive idea of closed subschemes in the affine case to develop closed subschemes in general. As with most of the properties of schemes we have considered so far, closed subschemes will be defined in terms of their associated morphisms, in this case closed embeddings. We will also define locally closed embeddings and look at the conditions under which an ideal sheaf of a scheme induces a closed embedding.
