Lecture Notes Posted for Chapter 7 (Partial)

I have posted the first 19 and change (a bit onto p. 20) pages of lecture notes for Chapter 7, which concerns dynamical systems on networks and which we will take all of week 7 and a large chunk (and maybe even all) of week 8 to cover. The material posted gets into some of what will be in week 8, so I remain on schedule as concerns posting notes.
