Short version: I’ve revised the first four chapters of Category Theory II.
Longer version for the three people who might care …! I’ve reorganized the early chapters of Part II into what is I think a more logical sequence, though that means there will be, for a moment, some broken cross-references and other oddities. And the first four chapters in the new order are significantly rewritten.
In keeping with what is, after all, supposed to be a gentle introduction, I’ve deleted some sections which were distractingly convoluted. In fact, as I get to work (slowly!) on Part II, my ambitions for it are becoming a bit more modest …
I used to tell grad students that their theses needn’t be great, they just needed to be finished. Likewise, I need to sternly tell myself, for these notes!
