Schemes 29: Invertible sheaves over the projective line
Channel: Richard E Borcherds
Date: 2020-07-22

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne.
In this lecture we classify the invertible sheaves over the projective line, 
and use them to show that several properties of quasiprojective sheaves over affine schemes do not hold for general schemes.
