Web3.4 It is enough to show that ˚ 1 is regular near ˚(1 : x 1: : x n), where ˚is the d-uple embedding. But near this point ˚ 1 takes (m 0: : m N) to (m i 0: : m i n) where m i k is the coordinate corresponding to the monomial xd 1 0 x k, and this is a regular map. 3.5 Identify Pnwith its image under the d-uple embedding.

WebSep 20, 2024 · I'm solving problems in Hartshorne. I don't know how to solve the following exercise (6.4 of Chapter 1): Let $Y$ be a nonsingular projective curve. Show that every nonconstant rational function $f$ on $Y$ defines a surjective morphism $\phi:Y\rightarrow \mathbb P^1$. I know I can use 6.7 and 6.8 to extend the morphism $f$ to such a $\phi$. WebAug 28, 2024 · My solution was as follows: Let h: X → Y × S Y be the map obtained by looking at f, g, then let Δ: Y → Y × S Y be the diagonal morphism. Since Y is separated it follows that Δ ( Y) is closed, and since h is continuous h − 1 ( Δ ( Y)) is closed, and one can show that U is a subset of h − 1 ( Δ ( Y)) so that it is equal to X. cherokee animal symbols and meanings
