I’m off to the Summer Topology Conference, North Bay, Ontario, Canada. I’ll be giving two talks there. One is directly related to Chapter 7 of the book, and may help get a global vision of what’s going on there: have a look at the slides. I’m also going to give another nifty talk, on a short proof of the Schröder-Simpson theorem (see the slides to see what that is); but that is not related to the book, rather to its sequel. After that, I’m on holidays: happy holidays to you all as well!
