Feb 6 (second update): I have also revised lectures 1 and 3. In lecture 1, there is a minor update to the statement of exercise 14b, and in lecture 3 I have replaced "weakly bipartite graph" with "weakly bipartite signed graph" in order to distinguish the notion from the one appearing in lecture 5.
