Started this so it’ll end up in the site eventually. I noticed I’m about halfway through the book and I’m coming close to the end of it’s point-set material. That lines up in parallel with the Algebraic Topology course I’ve been watching here, which is very good. I know this book (Gamelin & Green) jumps right into the Fundamental Group¹, but that course starts with intuitions about homotopy and chain complexes and I found that a much nicer way to start.

In any case, that’s going to help out a bunch with reading The Rising Sea, I started taking these notes as a way to sharpen my topology tools a bit and remind myself of the vocabulary, but I think this is going to be a collection of notes on a bunch of stuff, maybe do some cross-referencing as I go through. I have a \ggref macro I’ve been using to just keep general track of where things are, but properly threading these things through and maybe doing some nicer rendering would be cool.

It’ll be like Temu nLab.
