Oct 22, 2019 at 22:31 | comment | added | Y_q | I think you are right, I'm using Pic=Cl. Actually I encountered this when doing Hartshorne exercise 7.9, and indeed he assumed smoothness, but I don't know to what extent this condition can be weakened so that excision in Picard groups can be used, so that's why I said ''under some good conditions''. | |
