Chow's lemma [SEP] named after
Chow's lemma
Chow's lemma, named after Wei-Liang Chow, is one of the foundational results in algebraic geometry. It roughly says that a proper morphism is fairly close to being a projective morphism. More precisely, a version of it states the following:
Proof.
The proof here is a standard one (cf. ).
It is easy to reduce to the case when formula_1 is irreducible, as follows. formula_1 is noetherian since it is of finite type over a noetherian base. Then
paper of his on homogeneous spaces gives a beautiful treatment of the geometry known as the projective geometry of matrices and treated by elaborate calculations. His discussions are valid in a more general context."
