Seminar - Fall 2019

Combinatorics

John Baez

In the fall of 2019 I taught a course on combinatorics based on combinatorial species and their generating functions. These free books served as reading material:

Toward the end of this course I got so interested in the combinatorics of random permutations that I wrote a series of articles about them:

Here are hand-written notes for each class taken by Christian Williams, mixed in with notes on a more advanced seminar in which we developed some of the category-theoretic ideas in more detail.
