Course Schedule and Problem Sets
This is a tentative schedule for the course, and might change later in the semester. Remember to watch the videos before the meetings to be prepared to do the problem sets. You can see the videos by using the links below or by going to the Videos and lecture notes page
All videos were produced by Øyvind Solberg and obtained from the 2020 course page, while the layout and the (preliminary) schedule was taken from the 2021 course page.
