Seminar - Fall 2018

Category Theory

John Baez

I taught an introductory course on category theory Winter 2016 but this one is a bit more advanced, and less well organized. It focuses on the bar construction for monads, group cohomology, and their connection to categorification and 'homotopification'.

Here are hand-written notes for each class taken by Christian Williams. If you discover any errors in the notes please email me, and I'll add them to the list of errors.

You can also get hand-written notes by Kenny Courser for the lectures starting with Lecture 8 as a single file.
