Back from Cornwall, and I have now revised Chapters 1 to 14 of Beginning Category Theory. So here they are.
As before, to keep things simple, there is one long PDF with both the reworked chapters and the remaining unrevised chapters from the 2015/2018 Gentle Intro. I have added a little to Ch. 2, and tidied up Ch. 12. But the main revision this time is a much improved version of Chapter 14 on equalizers and co-equalizers. I’m still not entirely happy with it, but it is a heck of a lot better than it was. Enjoy!
Famous last words, but looking ahead, I think the next few chapters will be an easier job to revise, so I hope to now pick up speed again.
