| Dec 4, 2013 at 1:38 | comment | added | Piotr Achinger | 1) there is a canonical map $U\to Spec(O_X(U))$ which is universal (initial) among maps from $U$ to affine schemes, 2) even when $X$ is an affine and finite type over a field $k$, $O_X(U)$ might not be a finitely generated $k$-algebra (I don't remember the example though). | |
