| Feb 27, 2021 at 8:22 | comment | added | abx | The answer to the first question is yes. To define $C_1$ you embed $C$ into some affine space $\mathbb{A}^n$, take its closure $C_0$ in $\mathbb{P}^n\supset \mathbb{A}^n$, and normalize. Then $C_0\smallsetminus C$ is a hyperplane section of $C_0$, hence finite, and remains finite in the normalization. | |
