Schemes 31: Coherent sheaves
Channel: Richard E Borcherds
Date: 2020-07-23

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne.
We define coherent modules over rings and coherent sheaves,
and then discuss when the amps f* and f_* preserve coherence or quasicoherence.
