For example, an elliptic curve corresponding to y 2 = x 3 + a x + b will have partial map ( x, y) ↦ x, and this extends (uniquely) to a map of the full elliptic curve to P ...

WebJun 13, 2024 · A "closed immersion" between affine varieties is (by definition I guess) a morphism for which the corresponding morphisms of algebras is a surjection. Maybe some people will understand "closed embedding" to mean "closed immersion". You consider a closed morphism, which is injective. WebDec 24, 2014 · This is not an optimal solution, but if you didn't know that closed immersions can be checked affine locally (like I didn't), then this would be something you can do: check each condition for a closed immersion separately.
