Yes, the sequence is correct. 2. and 4. are dual, so it's really the same question. $\mathcal{O}_X(-D)$ is the ideal sheaf of D which is invertible. So $\mathcal{O}_D(-D)$ is its restriction to D as an invertible sheaf. It can also be understood as the cononormal sheaf. So then $\mathcal{O}_D(D)$ would be the normal sheaf and so on. I have go, but I hope that helps a little | |
