MA940 FAC Sheaves and coherent cohomology

This is a course of 30 advanced lectures I gave online in 2021 during the pandemic.
The lectures are far from perfect, but this is the kind of thing that we were
able to do during the long Covid lock-down, and some people have found
them useful since. The material is mostly cribbed from Jean-Pierre Serre's
famous paper cited below, with a considerable number of errors of my own invention.

The Warwick Math MA940 course description webpage is here.
A brief and jokey summary of the content, is given in Chapter B of my Park City lectures.
