Here is the link to the PCMI 2023 lecture notes and problem sets. The problem sets for the course were originally embedded into the lecture notes, instead of being self-contained. Here are the problems sets I distributed during the problem sessions, with select solutions.

Problem sets and solutions

1. Problem set 1: problem set, solutions
2. Problem set 2: problem set, solutions
3. Problem set 3: problem set, solutions
4. Problem set 4: problem set, solutions
