Examples
- The Picard group of the spectrum of a Dedekind domain is its ideal class group.
- The invertible sheaves on projective space Pn(k) for k a field, are the twisting sheaves so the Picard group of Pn(k) is isomorphic to Z.
- The Picard group of the affine line with two origins over k is isomorphic to Z.
