The Picard group of the spectrum of a Dedekind domain is its ideal class group. The invertible sheaves on projective space P n (k) for k a field, are the twisting sheaves (), so the Picard group of P n (k) is isomorphic to Z. The Picard group of the affine line with two origins over k is isomorphic to Z. Visa mer In mathematics, the Picard group of a ringed space X, denoted by Pic(X), is the group of isomorphism classes of invertible sheaves (or line bundles) on X, with the group operation being tensor product. This construction is a … Visa mer • Sheaf cohomology • Chow variety • Cartier divisor • Holomorphic line bundle Visa mer The construction of a scheme structure on (representable functor version of) the Picard group, the Picard scheme, is an important step in … Visa mer Let f: X →S be a morphism of schemes. The relative Picard functor (or relative Picard scheme if it is a scheme) is given by: for any S-scheme T, Visa mer WebbThe Picard group of projective variety Ask Question Asked 10 years, 4 months ago Modified 10 years, 4 months ago Viewed 1k times 9 If X is a smooth irreducible projective variety and its Picard group is 0, can we conclude that X is a point?
